Newly Discovered Object Could be a Leftover Apollo Rocket Stage Animations showing how J002E3 was captured into its current chaotic orbit around the Earth are available on the page linked in the image above. An analysis of the orbital motion of the newly discovered object J002E3 indicates that it could be a leftover Saturn V third stage from one of the Apollo missions, most likely the Apollo 12 mi
The following chart shows reported fireball events for which geographic location data are provided. Each event's calculated total impact energy is indicated by its relative size and by a color. Hover over an event to see its details. In 2019 it was determined that the Geostationary Lightning Mapper (GLM) instruments on GOES weather satellites can detect fireballs and bolides. The GLM Bolides websi
UPDATE! (April 2013) See notes below for preliminary 2012-2013 radar results and news Summary Researchers at NASA/JPL, Caltech, and Arecibo Observatory have released the results of radar observations of the potentially hazardous asteroid 99942 Apophis, along with an in-depth analysis of its motion. The research will affect how and when scientists measure, predict, or consider modifying the asteroi
The following table shows close approaches to the Earth by near-Earth objects (NEOs) limited as selected in the “Table Settings” below. Data are not available prior to 1900 A.D. nor after 2200 A.D. Data are further limited to encounters with reasonably low uncertainty. Check out our brief video tutorial. Object Object primary designation Close-Approach (CA) Date Date and time (TDB) of closest Eart
