The first two objects that were detected and had their Earth-MOID calculated before Earth impact were the small asteroids 2008 TC 3 and 2014 AA. 2014 AA is listed with a MOID of 0.00000045 AU (67 km; 42 mi), [5] and is the second smallest MOID calculated for an Apollo asteroid after 2020 QY 2 with an Earth-MOID of 0.00000039 AU (58 km; 36 mi).
The Hill sphere (gravitational sphere of influence) of the Earth is about 1,500,000 kilometers (0.01 AU) in radius, or approximately four times the average distance to the Moon. [12] [nb 2] This is the maximal distance at which the Earth's gravitational influence is stronger than the more distant Sun and planets. Objects orbiting the Earth must ...
Near-Earth asteroid (285263) 1998 QE 2 will pass Earth at a distance of 0.038 AU (5.7 million km; 3.5 million mi). [61] 2221 Triple conjunction of Mars and Saturn: 2223 December 2 At 12:39 UTC, Mars will occult Jupiter, this comes after a gap of 836 Earth years. [31] [42] 2227 Pluto's orbit takes it closer to the Sun than Neptune. [62] 2238/2239
Just one day before opposition, Jupiter will be around 367 million miles away from the Earth, the closest the two planets have been in 59 years, according to NASA. The last time that Jupiter was ...
This is because the distance between Earth and the Sun is not fixed (it varies between 0.983 289 8912 and 1.016 710 3335 au) and, when Earth is closer to the Sun , the Sun's gravitational field is stronger and Earth is moving faster along its orbital path. As the metre is defined in terms of the second and the speed of light is constant for all ...

The asteroid and comet belts orbit the Sun from the inner rocky planets into outer parts of the Solar System, interstellar space. [16] [17] [18] An astronomical unit, or AU, is the distance from Earth to the Sun, which is approximately 150 billion meters (93 million miles). [19]
Jupiter might have shaped the Solar System on its grand tack. In planetary astronomy, the grand tack hypothesis proposes that Jupiter formed at a distance of 3.5 AU from the Sun, then migrated inward to 1.5 AU, before reversing course due to capturing Saturn in an orbital resonance, eventually halting near its current orbit at 5.2 AU.
