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.
In such applications, radiative transfer codes are often called radiation parameterization. In these applications, the radiative transfer codes are used in forward sense, i.e. on the basis of known properties of the atmosphere, one calculates heating rates, radiative fluxes, and radiances. There are efforts for intercomparison of radiation codes.
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 ...
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 ...
Universe Sandbox is a series of interactive space sandbox gravity simulator educational software video games.Using 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 ...
The Double Asteroid Redirection Test (DART) was a NASA space mission aimed at testing a method of planetary defense against near-Earth objects (NEOs). [4] [5] It was designed to assess how much a spacecraft impact deflects an asteroid through its transfer of momentum when hitting the asteroid head-on. [6]

[12] [13] Such accounts assumed that a head-on impact would have destroyed both planets, creating a short-lived second asteroid belt between the orbits of Venus and Mars. In contrast, evidence published in January 2016 suggests that the impact was indeed a head-on collision and that Theia's remains are on Earth and the Moon. [14] [15] [16]
