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:

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)

What’s the Beer Price in Your Country?

Although fewer people have been able to grab a beer at the pub during this pandemic, the global desire for beer prevails. For example, sales of the Corona beer actually shot up in the past year, despite—or perhaps because of—associations with the coronavirus.

This World Beer Index from Expensivity compares the average price of a bottle of beer in 58 countries in a detailed map. Additionally, we show which countries spend the most on beer per capita, and just how much beer people really drink.

Pricey Pints: The Average Beer Price

Researchers calculated the average price of a typical bottle of beer (330ml, just shy of a pint) from well known brands via online stores and statistics database Numbeo. In addition, local beer prices were pulled from hotel and bar menus, and average values converted to USD.

In Qatar, you’d have to shell out $11.26 for a single beer, which would surely make for a really expensive night out on the town. In part, this is because in 2019, the Muslim-majority country introduced a 100% excise tax on top the previous sales price of all alcohol imports.

These steep prices are aimed at tourists—and with Qatar hosting the 2022 men’s soccer World Cup, there’ll be thousands of visitors in the country looking for a cold one at any price.

At just $1.68 per bottle, South Africa has the lowest average beer price thanks at least partially to cultural norms of buying in bulk.

Cashing In: The Per Capita Spend on Beer

The price of a single beer is one thing, but which countries spend the most on beer itself? Germany unsurprisingly tops the list here with nearly $2,000 of expenditures per capita, bolstered by its strong beer culture and annual Oktoberfest celebration.

Germany also prides itself on the purity of its beer—the vast majority of brewers follow the Reinheitsgebot, centuries-old purity laws that broadly state that beer may contain only three ingredients: water, barley, and hops.

Following closely behind is Poland, which spends $1,738 per capita. Meanwhile, the U.S. ranks eighth in the world for the highest spending on beer per capita at $1,554—beer is also the country’s most popular alcoholic beverage.

Getting Boozy: How Much Beer Do People Drink?

Using data from the World Health Organization, the visualization below also digs into how much beer is consumed around the world per capita.

The Czech Republic emerges on top in this regard, with 468 beers on average in a year—that works out to 1.3 beers per day. Spain and Germany are next with 417 and 411 beers, respectively.

On the flip side, people in Haiti only drink about four beers yearly. This may be because they prefer something a little stronger—97% of alcohol consumption in the nation comes from spirits such as rum.

Beer has been around for over 7,000 years. No matter the beer price in your country, it’s worth raising a glass to the timelessness of this humble beverage.

How Global Health and Wealth Has Changed Over 221 Years

At the dawn of the 19th century, global life expectancy was only 28.5 years.

Outbreaks, war, and famine would still kill millions of people at regular intervals. These issues are still stubbornly present in 21st century society, but broadly speaking, the situation around the world has vastly improved. Today, most of humanity lives in countries where the life expectancy is above the typical retirement age of 65.

At the same time, while inequality remains a hot button topic within countries, income disparity between countries is slowing beginning to narrow.

This animated visualization, created by James Eagle, tracks the evolution of health and wealth factors in countries around the world. For further exploration, Gapminder also has a fantastic interactive chart that showcases the same dataset.

The Journey to the Upper-Right Quadrant

In general terms, history has seen health practices improve and countries become increasingly wealthy–trends that are reflected in this visualization. In fact, most countries drift towards the upper-right quadrant over the 221 years covered in the dataset.

However, that path to the top-right, which indicates high levels of both life expectancy and GDP per capita, is rarely a linear journey. Here are some of the noteworthy events and milestones to watch out for while viewing the animation.

1880s: Breaking the 50-Year Barrier
In the late 19th century, Nordic countries such as Sweden and Norway already found themselves past the 50-year life expectancy mark. This was a significant milestone considering the global life expectancy was a full 20 years shorter at the time. It wasn’t until the year 1960 that the global life expectancy would catch up.

1918: The Spanish Flu and WWI
At times, a confluence of factors can impact health and wealth in countries and regions. In this case, World War I coincided with one of the deadliest pandemics in history, leading to global implications. In the animation, this is abundantly clear as the entire cluster of circles takes a nose dive for a short period of time.

1933, 1960: Communist Famines
At various points in history, human decisions can have catastrophic consequences. This was the case in the Soviet Union (1933) and the People’s Republic of China (1960), where life expectancy plummeted during famines that killed millions of people. These extreme events are easy to spot in the animation due to the large populations of the countries in question.

1960s: Oil Economies Kick into High Gear
During this time, Iran, Iraq, and Saudi Arabia all experience massive booms in wealth, and in the following decade, smaller countries such as the United Arab Emirates and Kuwait rocket to the right edge of the visualization.

In following decades, both Iran and Iraq can be seen experiencing wild fluctuations in both health and wealth as regime changes and conflict begin to destabilize the region.

1990s: AIDS in Africa
In the animation, a number of countries plummet in unison at the end of the 20th century. These are sub-Saharan African countries that were hit hard by the AIDS pandemic. At its peak in the early ’00s, the disease accounted for more than half of deaths in some countries.

1995: Breaking the 65-Year Barrier
Global life expectancy reaches retirement age. At this point in time, there is a clear divide in both health and wealth between African and South Asian countries and the rest of the world. Thankfully, that gap is would continue to narrow in coming years.

1990-2000s: China’s Economic Rise
With a population well over a billion people, it’s impossible to ignore China in any global overview. Starting from the early ’90s, China begins its march from the left to right side of the chart, highlighting the unprecedented economic growth it experienced during that time.

What the Future Holds

If current trends continue, global life expectancy is expected to surpass the 80-year mark by 2100. And, sub-Saharan Africa, which has the lowest life expectancy today, is expected to mostly close the gap, reaching 75 years of age.

Wealth is also expected to increase nearly across the board, with the biggest gains coming from places like Vietnam, Nigeria, and the Philippines. Some experts are projecting the world economy as a whole to double in size by 2050.

There are always bumps along the way, but it appears that the journey to the upper-right quadrant is still very much underway.
