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.
|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.

A Visual Guide to Human Emotion
For years, humans have attempted to categorize and codify human emotion. Here are those attempts, visualized.
A Visual Guide to Human Emotion
Despite vast differences in culture around the world, humanity’s DNA is 99.9% similar.
There are few attributes more central and universal to the human experience than our emotions. Of course, the broad spectrum of emotions we’re capable of experiencing can be difficult to articulate. That’s where this brilliant visualization by the Junto Institute comes in.
This circular visualization is the latest in an ongoing attempt to neatly categorize the full range of emotions in a logical way.
A Taxonomy of Human Emotion
Our understanding has come a long way since William James proposed four basic emotions – fear, grief, love, and rage—though these core emotions still form much of the foundation for current frameworks.
The wheel visualization above identifies six root emotions:
From these six emotions, more nuanced descriptions emerge, such as jealousy as a subset of anger, and awe-struck as a subset of surprise. In total, there are 102 second- and third-order emotions listed on this emotion wheel.
Reinventing the Feeling Wheel
The concept of mapping the range of human emotions on a wheel picked up traction in the 1980s, and has evolved ever since.
One of these original concepts was developed by American psychologist Robert Plutchik, who mapped eight primary emotions—anger, fear, sadness, disgust, surprise, anticipation, trust, and joy. These “high survival value” emotions were believed to be the most useful in keeping our ancient ancestors alive.
Another seminal graphic concept was developed by author Dr. Gloria Willcox. This version of the emotions wheel has spawned dozens of similar designs, as people continue to try to improve on the concept.
The more we research human emotion, the more nuanced our understanding becomes in terms of how we react to the world around us.
Researchers at UC Berkeley used 2,185 short video clips to elicit emotions from study participants. Study participants rated the videos using 27 dimensions of self-reported emotional experience, and the results were mapped in an incredible interactive visualization. It is interesting to note that some video clips garnered a wide array of responses, while other clips elicit a near unanimous emotional response.
Here are some example videos and the distribution of responses:
The data visualization clusters these types of videos together, giving us a unique perspective on how people respond to certain types of stimuli.
Much like emotion itself, our desire to understand and classify the world around us is powerful and uniquely human.
Mapping the World’s Key Maritime Choke Points
Ocean shipping is the primary mode of international trade. This map identifies maritime choke points that pose a risk to this complex logistic network.
Mapping the World’s Key Maritime Choke Points
Maritime transport is an essential part of international trade—approximately 80% of global merchandise is shipped via sea.
Because of its importance, commercial shipping relies on strategic trade routes to move goods efficiently. These waterways are used by thousands of vessels a year—but it’s not always smooth sailing. In fact, there are certain points along these routes that pose a risk to the whole system.
Here’s a look at the world’s most vulnerable maritime bottlenecks—also known as choke points—as identified by GIS.
What’s a Choke Point?
Choke points are strategic, narrow passages that connect two larger areas to one another. When it comes to maritime trade, these are typically straits or canals that see high volumes of traffic because of their optimal location.
Despite their convenience, these vital points pose several risks:
- Structural risks: As demonstrated in the recent Suez Canal blockage, ships can crash along the shore of a canal if the passage is too narrow, causing traffic jams that can last for days.
- Geopolitical risks: Because of their high traffic, choke points are particularly vulnerable to blockades or deliberate disruptions during times of political unrest.
The type and degree of risk varies, depending on location. Here’s a look at some of the biggest threats, at eight of the world’s major choke points.
Because of their high risk, alternatives for some of these key routes have been proposed in the past—for instance, in 2013 Nicaraguan Congress approved a $40 billion dollar project proposal to build a canal that was meant to rival the Panama Canal.
As of today, it has yet to materialize.
A Closer Look: Key Maritime Choke Points
Despite their vulnerabilities, these choke points remain critical waterways that facilitate international trade. Below, we dive into a few of the key areas to provide some context on just how important they are to global trade.
The Panama Canal
The Panama Canal is a lock-type canal that provides a shortcut for ships traveling between the Pacific and Atlantic oceans. Ships sailing between the east and west coasts of the U.S. save over 8,000 nautical miles by using the canal—which roughly shortens their trip by 21 days.
In 2019, 252 million long tons of goods were transported through the Panama Canal, which generated over $2.6 billion in tolls.
The Suez Canal
The Suez Canal is an Egyptian waterway that connects Europe to Asia. Without this route, ships would need to sail around Africa, which would add approximately seven days to their trips. In 2019, nearly 19,000 vessels, and 1 billion tons of cargo, traveled through the Suez Canal.
In an effort to mitigate risk, the Egyptian government embarked on a major expansion project for the canal back in 2015. But, given the recent blockage caused by a Taiwanese container ship, it’s clear that the waterway is still vulnerable to obstruction.
The Strait of Malacca
At its smallest point, the Strait of Malacca is approximately 1.5 nautical miles, making it one of the world’s narrowest choke points. Despite its size, it’s one of Asia’s most critical waterways, since it provides a critical connection between China, India, and Southeast Asia. This choke point creates a risky situation for the 130,000 or so ships that visit the Port of Singapore each year.
The area is also known to have problems with piracy—in 2019, there were 30 piracy incidents, according to private information group ReCAAP ISC.
The Strait of Hormuz
Controlled by Iran, the Strait of Hormuz links the Persian Gulf to the Gulf of Oman, ultimately draining into the Arabian Sea. It’s a primary vein for the world’s oil supply, transporting approximately 21 million barrels per day.
Historically, it’s also been a site of regional conflict. For instance, tankers and commercial ships were attacked in that area during the Iran-Iraq war in the 1980s.
The Bab el-Mandeb Strait
The Bab el-Mandeb Strait is another primary waterway for the world’s oil and natural gas. Nestled between Africa and the Middle East, the critical route connects the Mediterranean Sea (via the Suez Canal) to the Indian Ocean.
Like the Strait of Malacca, it’s well known as a high-risk area for pirate attacks. In May 2020, a UK chemical tanker was attacked off the coast of Yemen–the ninth pirate attack in the area that year.
Due to the strategic nature of the region, there is a strong military presence in nearby Djibouti, including China’s first ever foreign military base.
