Universe Sandbox is a series of simulation video games.In Universe Sandbox, users can see the effects of gravity on objects in the universe and run scale simulations of the Solar System, various galaxies or other simulations, while at the same time interacting and maintaining control over gravity, time, and other objects in the universe, such as moons, planets, asteroids, comets, and black holes.
Fomalhaut b was once suspected to be a planet, but is now suspected to be the remains of a planetary collision [6] P1121: F9V 80 yes [3] Before 2012 Two bodies with sizes of ≥100 km One hypervelocity impact [2] [7] NGC 2547–ID8: G6V 35 yes [3] late 2012 Two bodies with sizes of ≥100 km likely grazing or hit-and-run type event [7] [8 ...
OpenUniverse is a 3D Solar System simulator created by Raúl Alonso Álvarez. It uses OpenGL 1.1 (implemented through Mesa 3D) to simulate the Solar system in complete 3D, including its planets and their major and minor moons, along with a few asteroids with real 3D models created from real data.
The two-body problem is interesting in astronomy because pairs of astronomical objects are often moving rapidly in arbitrary directions (so their motions become interesting), widely separated from one another (so they will not collide) and even more widely separated from other objects (so outside influences will be small enough to be ignored safely).
After an analysis involving numerical simulations, the researchers concluded a planetary body about 435 miles (700 kilometers) in diameter, or roughly twice the size of Switzerland from east to ...

Amateur enthusiast spotted unusual light from star – and found that it was being covered by the dust from a vast collision Scientists watch afterglow from two huge planets crashing into each ...
The collision occurred at a distance of 2-16 AU (astronomical units) from the star. [3] [2] The infrared brightening is thought to be the result of dust produced by the disruption being heated by the collision, reaching a temperature of 1000 K (727°C; 1340°F) and then the dust slowly cooled off and expanded in size. Together with the newly ...
