Satellites in geostationary orbit. From the list in the first section, these are the closest known asteroids per year that approach Earth within one lunar distance.More than one asteroid per year may be listed if its geocentric distance [note 1] is within a tenth of the lunar distance, or 0.10 LD.
An Earth-crosser is a near-Earth asteroid whose orbit crosses that of Earth as observed from the ecliptic pole of Earth's orbit. [1] The known numbered Earth-crossers are listed here. Those Earth-crossers whose semi-major axes are smaller than Earth's are Aten asteroids; the remaining ones are Apollo asteroids. (See also the Amor asteroids.)
Asteroid (419624) 2010 SO 16, in a horseshoe companion orbit with Earth, is currently proximal to L 5 but at a high inclination. STEREO B (Solar TErrestrial RElations Observatory – Behind) made its closest pass to L 5 in October 2009, on its orbit around the Sun, slightly slower than Earth. [14]
NASA scientists flag locations along these objects paths as close approaches when they are slated to arrive at points within 4.6 million miles from the Earth's surface, which equates to roughly 19 ...
Before that, an asteroid named 2006 RH120, which orbits the sun and passes close to Earth every few decades, was captured by Earth’s gravity in June 2006 and stayed until around September 2007.
Apophis will come so close to Earth that it will be visible to the naked eye for around 2 billion people living across most of Europe, Africa and parts of Asia. To arrive at Apophis in February ...
The Amors have orbits strictly outside Earth's orbit: an Amor asteroid's perihelion distance (q) is greater than Earth's aphelion distance (1.017 AU). Amor asteroids are also near-earth objects so q < 1.3 AU. In summary, 1.017 AU < q < 1.3 AU. (This implies that the asteroid's semi-major axis (a) is also larger than 1.017 AU.)
Earth tends to pull asteroids into partial or full orbits around it regularly before they are flung back out into space. For instance, one such space rock 2022 NX 1 was a short-lived “mini-moon ...
