The pathway of the orbit has an eccentricity of 0.38 and an inclination of 3° with respect to the ecliptic. 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 ...
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.

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]
Utilizing this license, Keith Baker has published multiple non-official Eberron themed adventures and supplements for the 5th Edition on the Dungeon Masters Guild: Curtain Call: A Sharn Adventure (August 2018, PDF) [20] Trust No One (October 2018, PDF) [21] Morgrave Miscellany (March 2019, PDF) [22] [23]
In the Dungeons & Dragons (D&D) fantasy role-playing game, rule books contain all the elements of playing the game: rules to the game, how to play, options for gameplay, stat blocks and lore of monsters, and tables the Dungeon Master or player would roll dice for to add more of a random effect to the game. Options for gameplay mostly involve ...
The guide starts with an introduction that defines the physical boundaries of the Underdark, and also describes the intent and organization of the book and gives a brief list of D&D materials which have a strong connection to the Underdark. [12]
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.
Explorer's Guide to Wildemount (2020) is a sourcebook that details the continent of Wildemount from the Critical Role campaign setting for the 5th edition of the Dungeons & Dragons. Unlike the Critical Role: Tal'Dorei Campaign Setting , this sourcebook is considered "official" Dungeons & Dragons material since it was published by Wizards of the ...
