On 4 October 2022 Didymos made an Earth approach of 10.6 million km (6.6 million mi). [59] Dimorphos moves in a nearly equatorial, nearly circular orbit around Didymos, with an orbital period of 11.9 hours. Its orbit period is synchronous with its rotation, so that the same side of Dimorphos always faces Didymos.
Didymos is a binary asteroid with a satellite in its orbit. The minor-planet moon, named Dimorphos, [18] moves in a mostly circular retrograde orbit [19] with an orbital period of 11.9 hours. [11] [d] It measures approximately 160 meters (520 ft) in diameter compared to 780 meters (2,560 ft) for its primary (a mean diameter-ratio of 0.22). [20]
The collision shortened Dimorphos' orbit by 32 minutes, greatly in excess of the pre-defined success threshold of 73 seconds. [7] [8] [9] DART's success in deflecting Dimorphos was due to the momentum transfer associated with the recoil of the ejected debris, which was substantially larger than that caused by the impact itself. [10]
Small, rocky debris created when NASA intentionally slammed a spacecraft into an asteroid could create a new meteor shower that may be visible from Earth or Mars.
Hera is a spacecraft developed by the European Space Agency for its space safety program. Its primary mission objective is to study the Didymos binary asteroid system that was impacted four years earlier by the NASA Double Asteroid Redirection Test (DART) spacecraft and contribute to validation of the kinetic impact method to deviate a near-Earth asteroid from a colliding trajectory with Earth.
The result of the impact will be to change the orbital velocity and hence orbital period of Dimorphos, by a large enough amount that it can be measured from Earth. This will show for the first time that it is possible to change the orbit of a small 200-meter (660 ft) asteroid, around the size most likely to require active mitigation in the future.
This is a list of space probes that have left Earth orbit (or were launched with that intention but failed), organized by their planned destination. It includes planetary probes, solar probes, and probes to asteroids and comets, but excludes lunar missions, which are listed separately at List of lunar probes and List of Apollo missions.
God of War is an action-adventure game franchise created by David Jaffe and developed by Sony's Santa Monica Studio.It began in 2005 on the PlayStation 2 (PS2) video game console and has become a flagship series for PlayStation, consisting of nine installments across multiple platforms.
