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:
Source: Tabletop Whale
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.
|1||Ganymede||3,273 mi (5,268 km)||Jupiter's largest moon|
|2||Titan||3,200 mi (5,151 km)||Saturn's largest moon|
|3||Callisto||2,996 mi (4,821 km)||Jupiter's second largest moon|
|4||Io||2,264 mi (3,643 km)||Moon orbiting Jupiter|
|5||Moon||2,159 mi (3,474 km)||Earth's only moon|
|6||Europa||1,940 mi (3,122 km)||Moon orbiting Jupiter|
|7||Triton||1,680 mi (2,710 km)||Neptune's largest moon|
|8||Pluto||1,476 mi (2,376 km)||Dwarf planet|
|9||Eris||1,473 mi (2,372 km)||Dwarf planet|
|10||Titania||981 mi (1,578 km)||Uranus' largest moon|
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.

Ranked: America’s Best Universities
Evaluated on 19 different metrics, here’s the list of America’s best universities, led by 14 private schools.
Ranked: America’s Best Universities
The latest ranking of America’s best universities is here, perfectly timed for the approaching admissions season.
“Best” is of course subjective, and U.S. News and World Report has compiled 19 metrics on which they evaluated more than 400 national universities. Some of them include:
- Graduation rates & performance: A four-year rolling average of the proportion of each entering class earning a bachelor’s degree in six years or less. Performance is measured against predictions made by the publishers, and when beaten, the university gains a higher scoring.
- Peer assessment: A two-year weighted average of ratings from top academics—presidents, provosts and deans of admissions—on academic quality of peer institutions with which they are familiar.
- Financial resources: The average per student spend on instruction, research, student services and related educational expenditures in the 2021 fiscal year.
- Debt: A school’s average accumulated federal loan debt among borrowers only.
- Pell graduation rates & performance: the same calculation as stated above, but focused only on Pell Grant students, adjusted to give more credit to schools with larger Pell student proportions.
The website’s methodology section details how they sourced their data, the weights assigned to each metric, and their changes over the years.
From the hundreds assessed come the nearly 50 best universities that offer a variety of undergraduate majors, post-graduate programs, emphasize research, or award professional practice doctorates.
Which are the Best Universities in America?
At the top of the list, Princeton University is the best university in the country, known for its physics, economics, and international relations departments. Notably, it’s a rare Ivy league university that does not have a law, medical, or business school.
Here’s the full ranking of America’s best universities, along with annual tuition requirements.
|1||Princeton University||New Jersey||$59,710|
|7||Duke University||North Carolina||$66,172|
|9||Brown University||Rhode Island||$68,230|
|12||Columbia University||New York||$65,524|
|12||Cornell University||New York||$66,014|
|12||University of Chicago||Illinois||$65,619|
|18||Dartmouth College||New Hampshire||$65,511|
|20||University of Notre Dame||Indiana||$62,693|
Michigan, Ann Arbor
|22||Georgetown University||Washington, DC||$65,082|

Carolina at Chapel Hill
|North Carolina||$39,338 (out-state)

|53||Florida State University||Florida||$21,683 (out-state)
|53||William & Mary||Virginia||$48,841 (out-state)
MIT places second, and Harvard and Stanford tie for third. Yale rounds out the top five.
Private universities, including seven Ivy League colleges, dominate the top of the rankings. Meanwhile, the highest-ranked public schools are tied at 15th, both state schools in California.
For affordability, since the higher ranks are populated by private universities, there tends to be a broad correlation of better universities being more expensive. That said, the most expensive school in the top 50 ranks is actually the University of Southern California, tied at 28th, for $68,237/year.
As it happens, also tied at 28th, the University of Florida is the most affordable public school for in-state students ($6,381/year) and Florida State University tied at 53rd, is the most affordable for out-of-staters at $21,683/year.
However these costs are tuition-only, and don’t account for other necessary expenses: accommodation, food, and textbooks.
Best University versus Best “Fit”
Finding the best university for prospective students is more than just perusing a long ranking list.
Aside from the numerous schools present within each university—which can often be the best for specific majors—factors like location, proximity to family, campus culture, the non-academic pursuits (sports, extracurriculars, internships) are also taken into consideration.
In fact, research has found that just attaining a university degree improves future earnings potential and employability.
Furthermore, individual engagement at college (irrespective of the rank of the school in question) plays a far bigger role in learning and general well-being than simply attending a highly-ranked school.
However, for low income and minority students, attending a top-ranked school does improve future earnings considerably. For women, it also often results in delaying marriage and kids, which results in more work-hours and as a result, more pay.
