Occator / ɒ ˈ k eɪ t ər / is an impact crater located on Ceres, the largest object in the main asteroid belt that lies between the orbits of Mars and Jupiter, that contains "Spot 5", the brightest of the bright spots observed by the Dawn spacecraft. It was known as "Region A" in ground-based images taken by the W. M. Keck Observatory on ...
As with many craters on Ceres, Haulani has been extensively modified by mass wasting processes, with landslide deposits from the crater rim covering parts of its floor. It is one of the youngest large craters on Ceres, estimated to have been formed between 1.7 and 5.9 million years ago. As a result, it is one of Ceres's brightest surface features.
This is a list of asteroids that have impacted Earth after discovery and orbit calculation that predicted the impact in advance. As of December 2024 [update] , all of the asteroids with predicted impacts were under 5 m (16 ft) in size that were discovered just hours before impact, and burned up in the atmosphere as meteors .
Kerwan (/ ˈ k ɜːr w ə n /) is the largest confirmed impact basin and one of the largest geological features on the dwarf planet Ceres. It was discovered on February 19, 2015 from Dawn images as it approached Ceres. The crater is distinctly shallow for its size, and lacks a central peak.
Dawn 's images led to widespread reports in the media about the bright spots, including in news sources, [22] astronomy magazines, [23] and science magazines. [24] An informal NASA poll during May offered the following ideas for the nature of the spots: [ 25 ] ice, volcanos, geysers, salt deposits, rock, or other.
More than a century ago, something exploded in the sky above Siberia, breaking windows and creating a shining ball of light – but was it a meteor impact? Strange new theory of what caused ...
Asteroid impact prediction is the prediction of the dates and times of asteroids impacting Earth, along with the locations and severities of the impacts. The process of impact prediction follows three major steps: Discovery of an asteroid and initial assessment of its orbit which is generally based on a short observation arc of less than 2 weeks.
