The satellite of the asteroid Didymos received its official name – Dimorph. In 2021, DART and Hera probes will be sent to it. Information about this appeared on the website of the International Astronomical Union (IAU).
According to the official announcement by the IAU, Dimorph is translated from Greek as having two forms. The satellite is less than half of the Didymos system.
This is the first celestial body in the history of space, the shape of which will change after a collision with a DART probe. This will happen in 2022. This clash is inevitable. The fact is that in February 2013, mission leaders chose a target – a dangerous near-Earth asteroid Didymos. It is likely that he will collide with the Earth in a hundred years. Scientists had hoped to prevent this by changing its orbit through a collision with a DART probe in 2022. In 2026, scientists will look at the results of their operation with the Hera probe in 2026.
An object threatening the Earth consists of two halves. the main body with a diameter of 800 m and a satellite of 150 m in size, which rotate around each other at a distance of about 1.1 km. Previously, the satellite did not have an official name, because of this there was confusion in the scientific community.
Astronomers expect to see the first consequences of an artificial collision already in 2022 due to the fact that together with the DART probe, the LICIACube microsatellite will be sent to Didymos and Dimorph. He will transmit to Earth a video of the collision of the probe and the asteroid.
