Visualized: The Mass of the Entire Solar System

In space, everything feels weightless due to the lack of gravity.

So how do you measure the weight of objects in space? You don’t. When it comes to the cosmos, all that matters is mass.

Today’s interactive data visualization comes from Reddit user Ranger-UK, and is designed by Daniel Caroli. It delves into the different masses which make up our solar system, and how they all compare in size.

A Star Is Born

Perhaps not surprisingly, the Sun eclipses all other nearby objects by mass. At the heart of our solar system, this yellow dwarf’s gravity is what holds it all together.

The Sun actually makes up 99.8% of our entire solar system’s mass — and we’re lucky to be living in the other 0.2%. Responsible for all life on Earth, it’s no wonder that various cultures have worshiped the Sun throughout history, and even dedicated deities to it.

Currently in its middle years — the sun is over four billion years old, and it’s predicted to remain stable for another five billion years. After this, it will overtake the orbits of Mercury and Venus and then shrink back to the size of a white dwarf.

Out Of This World

The gas giants are all more than ten times as massive as Earth, even though they’re mainly made up of hydrogen and helium. They dominate the Solar System’s real estate — once the Sun is taken out of the equation, of course.

In order, here’s how the planets stack up:

PlanetCategoryMassRadiusDensity

MercuryTerrestrial planet330 x 10²¹ kg2,439.7 ±1 km5.427g/cm³

Satellites Out of Control

The further away from the Sun you go, the more moons can be found orbiting planets. Earth’s singular moon is the fifth largest of almost 200 natural satellites found in the solar system.

Mars has two moons that don’t make it into the visualization above due to their low masses:

  • Phobos: 1.08×10^16 kg
  • Deimos: 2.0×10^15 kg

Here’s a breakdown of some other moons out there:

  • Jupiter
    Total named: 53
    Biggest moons: Ganymede, Callisto, Io, Europa
    These four can be seen easily with some help from binoculars.
  • Saturn
    Total named: 53
    Biggest moons: Titan, Rhea, Iapetus, Dione, and Tethys
  • Uranus
    Total named: 27
    Biggest moons: Titania, Oberon, Ariel, Umbriel
  • Neptune
    Total named: 14
    Biggest moon: Triton, which is as big as the dwarf planet Pluto.

Pluto and some “leftovers” of the solar system lie in the distant region of the doughnut-shaped Kuiper belt, between 30 to 50 astronomical units (AU) away. Beginning at the orbit of Neptune, the belt encompasses some of those objects in the visualization categorized as “other”.

So far, we’ve only managed to set foot on our own moon. NASA’s Opportunity rover helped us explore the Red Planet virtually for over 14 years, while the Curiosity is still going strong.

Who knows what else lurks beyond the edges of our solar system?

It suddenly struck me that that tiny pea, pretty and blue, was the Earth… I didn’t feel like a giant. I felt very, very small.

— Neil Armstrong, looking back at the Earth from the Moon (July 1969)

Mainstream EV Adoption: 5 Speedbumps to Overcome

The pace of mainstream EV adoption has been slow, but is expected to accelerate as automakers overcome these five critical challenges.

Mainstream EV Adoption: 5 Speedbumps to Overcome

Many would agree that a global shift to electric vehicles (EV) is an important step in achieving a carbon-free future. However, for various reasons, EVs have so far struggled to break into the mainstream, accounting for just 2.5% of global auto sales in 2019.

To understand why, this infographic from Castrol identifies the five critical challenges that EVs will need to overcome. All findings are based on a 2020 survey of 10,000 consumers, fleet managers, and industry specialists across eight significant EV markets.

The Five Challenges to EV Adoption

Cars have relied on the internal combustion engine (ICE) since the early 1900s, and as a result, the ownership experience of an EV can be much more nuanced. This results in the five critical challenges we examine below.

Challenge #1: Price

The top challenge is price, with 63% of consumers believing that EVs are beyond their current budget. Though many cheaper EV models are being introduced, ICE vehicles still have the upper hand in terms of initial affordability. Note the emphasis on “initial”, because over the long term, EVs may actually be cheaper to maintain.

Taking into account all of the running and maintenance costs of [an EV], we have already reached relative cost parity in terms of ownership.

—President, EV consultancy, U.S.

For starters, an EV drivetrain has significantly fewer moving parts than an ICE equivalent, which could result in lower repair costs. Government subsidies and the cost of electricity are other aspects to consider.

So what is the tipping price that would convince most consumers to buy an EV? According to Castrol, it differs around the world.

CountryEV Adoption Tipping Price ($)
🇯🇵 Japan$42,864
🇨🇳 China $41,910
🇩🇪 Germany$38,023
🇳🇴 Norway$36,737
🇺🇸 U.S.$35,765
🇫🇷 France$31,820
🇮🇳 India$30,572
🇬🇧 UK$29,883
Global Average$35,947

Many budget-conscious buyers also rely on the used market, in which EVs have little presence. The rapid speed of innovation is another concern, with 57% of survey respondents citing possible depreciation as a factor that prevented them from buying an EV.

Challenge #2: Charge Time

Most ICE vehicles can be refueled in a matter of minutes, but there is much more uncertainty when it comes to charging an EV.

Using a standard home charger, it takes 10-20 hours to charge a typical EV to 80%. Even with an upgraded fast charger (3-22kW power), this could still take up to 4 hours. The good news? Next-gen charging systems capable of fully charging an EV in 20 minutes are slowly becoming available around the world.

Similar to the EV adoption tipping price, Castrol has also identified a charge time tipping point—the charge time required for mainstream EV adoption.

CountryCharge Time Tipping Point (minutes)
🇮🇳 India35
🇨🇳 China34
🇺🇸 U.S.30
🇬🇧 UK30
🇳🇴 Norway29
🇩🇪 Germany29
🇯🇵 Japan29
🇫🇷 France27
Global Average31

If the industry can achieve an average 31 minute charge time, EVs could reach $224 billion in annual revenues across these eight markets alone.

Challenge #3: Range

Over 70% of consumers rank the total range of an EV as being important to them. However, today’s affordable EV models (below the average tipping price of $35,947) all have ranges that fall under 200 miles.

Traditional gas-powered vehicles, on the other hand, typically have a range between 310-620 miles. While Tesla offers several models boasting a 300+ mile range, their purchase prices are well above the average tipping price.

For the majority of consumers to consider an EV, the following range requirements will need to be met by vehicle manufacturers.

CountryRange Tipping Point (miles)
🇺🇸 U.S.321
🇳🇴 Norway315
🇨🇳 China300
🇩🇪 Germany293
🇫🇷 France289
🇯🇵 Japan283
🇬🇧 UK283
🇮🇳 India249
Global Average291

Fleet managers, those who oversee vehicles for services such as deliveries, reported a higher average EV tipping range of 341 miles.

Challenge #4: Charging Infrastructure

Charging infrastructure is the fourth most critical challenge, with 64% of consumers saying they would consider an EV if charging was convenient.

Similar to charge times, there is much uncertainty surrounding infrastructure. For example, 65% of consumers living in urban areas have a charging point within 5 miles of their home, compared to just 26% for those in rural areas.

Significant investment in public charging infrastructure will be necessary to avoid bottlenecks as more people adopt EVs. China is a leader in this regard, with billions spent on EV infrastructure projects. The result is a network of over one million charging stations, providing 82% of Chinese consumers with convenient access.

Challenge #5: Vehicle Choice

The least important challenge is increasing the variety of EV models available. This issue is unlikely to persist for long, as industry experts believe 488 unique models will exist by 2025.

Despite variety being less influential than charge times or range, designing models that appeal to various consumer niches will likely help to accelerate EV adoption. Market research will be required, however, because attitudes towards EVs vary by country.

CountryConsumers Who Believe EVs Are More Fashionable Than ICE Vehicles (%)
🇮🇳 India70%
🇨🇳 China68%
🇫🇷 France46%
🇩🇪 Germany40%
🇺🇸 UK40%
🇯🇵 Japan39%
🇺🇸 U.S.33%
🇳🇴 Norway 31%
Global Average48%

A majority of Chinese and Indian consumers view EVs more favorably than traditional ICE vehicles. This could be the result of a lower familiarity with cars in general—in 2000, for example, China had just four million cars spread across its population of over one billion.

EVs are the least alluring in the U.S. and Norway, which coincidentally have the highest GDP per capita among the eight countries surveyed. These consumers may be accustomed to a higher standard of quality as a result of their greater relative wealth.

So When Do EVs Become Mainstream?

As prices fall and capabilities improve, Castrol predicts a majority of consumers will consider buying an EV by 2024. Global mainstream adoption could take slightly longer, arriving in 2030.

Caution should be exhibited, as these estimates rely on the five critical challenges being solved in the short-term future. This hinges on a number of factors, including technological change, infrastructure investment, and a shift in consumer attitudes.

New challenges could also arise further down the road. EVs require a significant amount of minerals such as copper and lithium, and a global increase in production could put strain on the planet’s limited supply.

Unsurprisingly, McDonald’s comes in at number one with over $40 billion in sales. Despite a scandal involving its former CEO, McDonald’s still managed to significantly outsell its peers—the company made almost double that of the second-largest fast food chain, Starbucks.

But don’t worry, Starbucks did just fine for itself. With $21 billion in sales, the Seattle-based coffee chain saw a 5% increase compared to its numbers in 2018.

Top Selling Fast Food Categories

Based on the ranking, it’s clear that Americans still love their McDonald’s. But are burgers, in general, the most popular fast food item?

In short—yes. Burgers are king. Here’s a look at how burgers, pizza, chicken, and other food categories measure up:

Burger joints remain the most popular fast food option among consumers—14 of the 50 chains on the list are classified as burger restaurants, with $80 billion in collective sales.

Snacks come in at second place, with a total of $36 billion in revenue. Boasting a broad variety of foods from iced coffee to donuts and ice cream, six of the restaurants on the list are included in this category. Starbucks is the most popular, followed by Dunkin’ and Dairy Queen respectively.

While the chicken and sandwich categories both have nine restaurants included in the ranking, chicken restaurants outsold sandwiches by almost $1 billion. This is largely due to Chick-fil-A, which makes up more than a third of all chicken restaurant sales included in the ranking.

COVID Closures

It’s important to note that these numbers reflect the fast food industry before the devastating impacts of COVID-19. The global pandemic has forced many fast food restaurants to adapt, and it’s also triggered a number of restaurant shutdowns.

For instance, McDonald’s is set to permanently close 200 of its 14,000 U.S. locations, and Dunkin’ will be closing 450 restaurants by the end of 2020. Starbucks has also announced it’s planning to permanently shut down up to 400 locations by mid-2021.

With online sales more important than ever, the chains with a strong digital presence may be in a better position to weather the storm. Chains with physical distancing options, such as drive-throughs, could also recover quicker.
