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.

Ever since we learned that an asteroid sucker punched the dinosaurs 66 million years ago, we’ve been a little bit worried it might happen again, but with us in the crosshairs. Countless movies ...
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.
The actual origins of the game are not clear; some of the earliest documentation comes from 1893, when Stewart Culin reported that Cee-lo was the most popular dice game played by Chinese-American laborers, although he also notes they preferred to play Fan-Tan and games using Chinese dominoes such as Pai Gow or Tien Gow rather than dice games.
Liar's dice is a class of dice games for two or more players in which deception is a significant gameplay element. In "single hand" liar's dice games, each player is given a set of dice, all players roll once, and the bids relate to the dice each player can see (their hand) plus all the concealed dice (the other players' hands).
Patterned after the success of collectible card games, a number of collectible dice games have been published. [1] Although most of these collectible dice games are long out-of-print, there is still a small following for many of them. Some collectible dice games include: Battle Dice; Dice Masters; Diceland; Dragon Dice
Four-faced Daldøs dice. A third form of d4s are long dice shaped like rectangular prisms, as used in the Scandinavian game daldøs. Landing on end may be rendered very rare simply by their small size relative to the faces, by the instability implicit in the height of the dice, and by rolling the long dice along their axes rather than tossing.
