Universe Sandbox · published · build 19674741
Watch the third-ever discovered visitor from outside our Solar System, 3I/ATLAS, fly past the Sun and see how it compares it to other known interstellar interlopers. We’ve also improved the view that shows what parts of the surface of a planet are illuminated, updated our scientific notation, and more!
The Daylight view now shows surface illumination of a planet in real-time as the object rotates and orbits within the simulation. Previously it was a static snapshot of the daylight on a planet.
Before
After
Watch the comet 3I/ATLAS, the third-ever discovered interstellar visitor to our Solar System, pass by on its journey through space and compare the trajectories of all three known interstellar visitors. Find them under
Home > Open > Interstellar Comet 31/ATLAS
Home > Open > Interstellar Object Trajectory Comparison
Astronomically large (and small) numbers are already hard to understand, so we’ve updated our scientific notation to be friendlier: “1 × 10^#" (previously we used “1E+#”). Try changing Earth’s mass to 1x10^6 Earth masses and see what happens to the Solar System.
Before
After
Watch what would happen to Earth if the Moon were replaced with a black hole of the same mass or the same radius. Which simulation do you think will be more destructive? Check them out under
Home > Open > Earth with a Black Hole Moon | Same Mass
Home > Open > Earth with a Black Hole Moon | Same Radius
See small objects in your simulation even faster by turning on Markers by pressing “m” (previously “i”) on your keyboard. No need to go all the way to View > Markers.
You can once again add custom colors to your human scale objects to make purple cows and pigeon rainbow.
