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:
|Jupiter||Gas giant||1,898,600 x 10²¹ kg||69,911 ±6 km||1.326g/cm³|
|Saturn||Gas giant||568,460 x 10²¹ kg||58,232 ±6 km (*without rings)||0.687g/cm³|
|Neptune||Gas giant||102,430 x 10²¹ kg||24,622 ±19 km||1.638g/cm³|
|Uranus||Gas giant||86,832 x 10²¹ kg||25,362 ±7 km||1.27g/cm³|
|Earth||Terrestrial planet||5,974 x 10²¹ kg||6.371 ±0.01 km||5.514g/cm³|
|Venus||Terrestrial planet||4,869 x 10²¹ kg||6,051.8 ±1 km (*without gas)||5.243g/cm³|
|Mars||Terrestrial planet||642 x 10²¹ kg||3,389.5 ±0.2 km||3.9335g/cm³|
|Mercury||Terrestrial planet||330 x 10²¹ kg||2,439.7 ±1 km||5.427g/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:
Total named: 53
Biggest moons: Ganymede, Callisto, Io, Europa
These four can be seen easily with some help from binoculars.
Total named: 53
Biggest moons: Titan, Rhea, Iapetus, Dione, and Tethys
Total named: 27
Biggest moons: Titania, Oberon, Ariel, Umbriel
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.

The Best and Worst Performing Sectors in 2019
The U.S. stock market had a banner year, but some sectors were notable outliers. Here are the ones that outperformed (and underperformed) in 2019.
The Best and Worst Performing Sectors in 2019
If you think back almost 12 months, you’ll remember that the markets opened the year with extreme levels of volatility.
Stocks had just finished the worst year in a decade. Then in early January, Apple cut its earnings guidance after the company had already lost over $400 billion in market capitalization. The S&P 500 and DJIA seesawed, suggesting that the lengthy bull run could come to an end.
Yet, here we are a year later — we’re wrapping up the decade with a banner year for the S&P 500. As of the market close on December 30, 2019, stocks were up 28.5% to give the index what is expected to be its second-best performance since 1998.
Winners and Losers
Today’s infographic pulls data from Finviz.com. We’ve taken their great treemap visualization of U.S. markets and augmented it to show the sectors that beat the frothy market in 2019, as well as the ones that lagged behind.
Below, we’ll highlight instances where sectors stood out as having companies that, with few exceptions, saw ubiquitously positive or negative returns.
Top Performing Sectors
Semiconductor stocks soared in 2019, despite sales expected to shrink 12% globally. Although this seems counterintuitive at first glance, the context helps here: in 2018, there was hefty correction in the market – and the future outlook for the industry has also been revised to be rosier.
2. Credit Services
In case you didn’t get the memo, the world is increasingly going cashless — and payments companies have been licking their lips. Mastercard, Visa, American Express, Capital One, and Discover were just some of the names that outperformed the S&P 500 in 2019.
3. Aerospace / Defense
The vast majority of companies in this market, including Lockheed Martin, Raytheon, and United Technologies, all beat the market in 2019. One notable and obvious exception to this is Boeing, a company that saw its stock get hammered after the Boeing 737 Max model was grounded in the wake of several high-profile crashes.
4. Electronic Equipment
Apple shareholders had a bit of a wild ride in 2018. The company had risen in value to $1.1 trillion, but then it subsequently lost over $400 billion in market capitalization by the end of the year. Interestingly, in 2019, the stock had a strong bounce back year: the stock increased 84.8% in value, making it the best-performing FAANG stock by far.
5. Diversified Machinery
Manufacturers such as Honeywell, General Electric, Cummins, and Danaher saw solid double-digit gains in 2019, despite a slowing U.S. industrial sector. For GE in particular, this was a bit of a comeback year after its stock was decimated in 2018.
Construction Materials, Medical Labs & Research, Gold, Medical Appliances, Insurance Brokers
Worst Performing Sectors
Big oil, independent oil, and many oil services companies all had a year to forget. While this is not unusual in a highly cyclical industry, what is strange is that this happened in a year where oil prices (WTI) increased 36% for the best year since 2016.
2. Wireless Communications
Growing anticipation around 5G was not enough to buoy wireless companies in 2019.
3. Foreign Banks
It’s a tough environment for European banks right now. Not only is it late in the cycle, but banks are trying to make money in an environment with negative rates and large amounts of Brexit uncertainty. The strong U.S. dollar doesn’t help much, either.
The CEO of The Gap has described U.S. tariffs as “attacks on the American consumer”, providing just another nail in the coffin to the bottom line of the retail industry. Given these additional headwinds, it’s not surprising that companies like The Gap, American Eagle, Nordstrom, Urban Outfitters, and Abercrombie & Fitch all finished the year in the red.
5. Foreign Telecoms
Continued strength of the U.S. dollar weighed on foreign telecoms, which make the majority of their revenues in other currencies.
Visualizing the Decline of Confidence in American Institutions
Americans rely on several institutions for their services and safety—but how has their confidence in institutions changed since 1975?
Every day, the public relies on a number of major institutions for services and safety. From banks and governments, to media and the military—these institutions play an important role in shaping life as we know it.
Yet, today’s interactive data visualization from Overflow Data shows that America’s confidence in institutions has drastically waned. The data relies on the General Social Survey (GSS) to provide a 40-year overview of how sentiment has changed with respect to 13 different institutions.

The Erosion of Confidence
Overall, confidence in most institutions has eroded. Americans find it especially hard to trust their government: the “great deal of confidence” metrics for Congress, the Supreme Court, and the Executive Branch were low to begin with, and have declined further since 1975.
That said, the biggest overall drop belongs to the press, which saw 50% of surveyed Americans saying they have “hardly any confidence” in it in 2016. This is nearly a three-fold increase from 1975, when that number was just 19%. Of course, with the rise of fake news in more recent years, the erosion of confidence in media doesn’t seem to be slowing down.
Here’s a look at the two extremes of sentiment regarding the studied institutions, showing how the opposite measures of “hardly any confidence” and a “great deal of confidence” have changed since 1975:
|🏦 Banks & Financial Institutions||Hardly any||10.9%||31.2%||+20.3 p.p.|
|Great deal||32.3%||14.1%||-18.2 p.p.|
|🗳️ Congress||Hardly any||26.2%||52.6%||+26.4 p.p.|
|Great deal||13.6%||5.9%||-7.7 p.p.|
|🏫 Education||Hardly any||13.0%||17.5%||+4.5 p.p.|
|Great deal||31.5%||25.6%||-5.9 p.p.|
|🏛️ Executive Branch||Hardly any||29.7%||42.4%||+12.7 p.p.|
|Great deal||13.4%||12.8%||-0.6 p.p.|
|🏬 Major Companies||Hardly any||22.9%||17.3%||-5.6 p.p.|
|Great deal||20.5%||18.3%||-2.2 p.p.|
|🏥 Medicine||Hardly any||17.8%||13.4%||-4.4 p.p.|
|Great deal||51.8%||50.6%||-1.2 p.p.|
|🎖️ Military||Hardly any||14.8%||7.6%||-7.2 p.p.|
|Great deal||36.3%||53.4%||+17.1 p.p.|
|💪 Organized Labor||Hardly any||31.5%||22.6%||-8.9 p.p.|
|Great deal||10.2%||13.9%||+3.7 p.p.|
|🙏 Religion||Hardly any||23.0%||26.4%||+3.4 p.p.|
|Great deal||25.8%||20.0%||-5.8 p.p.|
|📰 Press||Hardly any||19.0%||50.0%||+31 p.p.|
|Great deal||24.5%||7.6%||-16.9 p.p.|
|🥼 Scientific Community||Hardly any||7.4%||6.1%||-1.3 p.p.|
|Great deal||41.7%||42.1%||+0.4 p.p.|
|📺 Television||Hardly any||23.4%||43.1%||+19.7 p.p.|
|Great deal||18.4%||9.8%||-8.6 p.p.|
|⚖️ U.S. Supreme Court||Hardly any||19.2%||17.4%||-1.8 p.p.|
|Great deal||31.8%||26.3%||-5.5 p.p.|
Banks and financial institutions have also suffered a bad rep in the public eye. Their “great deal of confidence” metric has dropped sharply from 32.3% to 14.1% in four decades.
One major exception is the military, which emerges as the most trusted institution. Americans’ faith in the military has also shown the most improvement, with a 17.1 p.p increase in a “great deal of confidence” since 1975.
The Split Widens Further
While measuring public confidence in institutions can be subjective, it provides an understanding of where Americans want to see change and reform take place.
