A Map of Every Object in Our Solar System

The path through the solar system is a rocky road.

Asteroids, comets, planets and moons and all kinds of small bodies of rock, metals, minerals and ice are continually moving as they orbit the sun. In contrast to the simple diagrams we’re used to seeing, our solar system is a surprisingly crowded place.

In this stunning visualization, biologist Eleanor Lutz painstakingly mapped out every known object in Earth’s solar system (>10km in diameter), hopefully helping you on your next journey through space.

Data-Driven Solar System

This particular visualization combines five different data sets from NASA:

From this data, Lutz mapped all the orbits of over 18,000 asteroids in the solar system, including 10,000 that were at least 10km in diameter, and about 8,000 objects of unknown size.

This map shows each asteroid’s position on New Year’s Eve 1999.

The Pull of Gravity

When plotting the objects, Lutz observed that the solar system is not arranged in linear distances. Rather, it is logarithmic, with exponentially more objects situated close to the sun. Lutz made use of this observation to space out their various orbits of the 18,000 objects in her map.

What she is visualizing is the pull of the sun, as the majority of objects tend to gravitate towards the inner part of the solar system. This is the same observation Sir Isaac Newton used to develop the concept of gravity, positing that heavier objects produce a bigger gravitational pull than lighter ones. Since the sun is the largest object in our solar system, it has the strongest gravitational pull.

If the sun is continually pulling at the planets, why don’t they all fall into the sun? It’s because the planets are moving sideways at the same time.

Without that sideways motion, the objects would fall to the center – and without the pull toward the center, it would go flying off in a straight line.

This explains the clustering of patterns in solar systems, and why the farther you travel through the solar system, the bigger the distance and the fewer the objects.

The Top Ten Non-Planets in the Solar System

We all know that the sun and the planets are the largest objects in our corner of the universe, but there are many noteworthy objects as well.

While the map only shows objects greater than 10 kilometers in diameter, there are plenty of smaller objects to watch out for as well.

An Atlas of Space

This map is one among many of Lutz’s space related visualizations. She is also in the process of creating an Atlas of Space to showcase her work.

As we reach further and further beyond the boundaries of earth, her work may come in handy the next time you make a wrong turn at Mars and find yourself lost in an asteroid belt.

Mapped: Chinese Provinces With Cities Over 1 Million People

Some Chinese provinces are so populous they rival entire countries. But how many of them have cities over a million people?

Almost two-thirds of the 1.4 billion Chinese population lives in an urban area. But how does this play out across the country’s geography?

This map shows the Chinese provinces with cities over a million residents. Data for this graphic is sourced from citypopulation.de.

Ranked: Chinese Provinces With Cities Over 1 Million People

China’s Guangdong province has 17 cities with a population size of 1 million or more. It is also China’s most populous province, home to 127 million people. This makes it comparable to the size of Japan, the 12th most populous country in the world.

Jiangsu, ranked fourth in population overall, is the only other province which has 10+ cities with a million or more inhabitants.

Meanwhile, some of China’s most populous cities—Shanghai, Beijing, Tianjin, and Chongqing—are administered directly by the central government, and do not fall under provincial control.

In fact, Shanghai and Beijing have informal “population caps” to prevent them from growing larger, in a bid to reduce pollution, overcrowding, and pressure on public services.

On the other hand, Tibet’s cold climes and rugged terrain make for a sparsely-populated area, totalling 3 million people across 1.2 million km². Tibet is the only province-level division in China without a single city over a million residents.

All together, China has 105 cities with more than one million inhabitants. For comparison, India has 65, and the U.S. has nine.
