At perihelion, Earth is roughly 91.4 million miles away from the sun. On average, the planet is separated from the sun by a distance of approximately 93 million miles.
The asteroid has an orbital period of about 4.05 years and an orbital inclination of 3.45 degrees with respect to Earth's orbit . [3] The asteroid came to perihelion (closest approach to the Sun) on 22 November 2024. The asteroid made a close approach to Earth on 25 December 2024, two days before its discovery.
[nb 1] Earth's orbital speed averages 29.78 km/s (19 mi/s; 107,208 km/h; 66,616 mph), which is fast enough to cover the planet's diameter in 7 minutes and the distance to the Moon in 4 hours. [3] The point towards which the Earth in its solar orbit is directed at any given instant is known as the "apex of the Earth's way". [4] [5]
As the two dates chosen here are equinoxes, this will be correct when perihelion, the date the Earth is closest to the Sun, falls on a solstice. The current perihelion, near January 4, is fairly close to the solstice of December 21 or 22.
Comet ATLAS reached perihelion, its closest point to the Sun, on Jan. 13. From now on, it will get dimmer in the night sky each day. The view for those of us down on Earth won’t be as clear as ...
Earth's rotation axis moves with respect to the fixed stars (inertial space); the components of this motion are precession and nutation. It also moves with respect to Earth's crust; this is called polar motion. Precession is a rotation of Earth's rotation axis, caused primarily by external torques from the gravity of the Sun, Moon and other bodies.
The apsides refer to the farthest (2) and nearest (3) points reached by an orbiting planetary body (2 and 3) with respect to a primary, or host, body (1). An apsis (from Ancient Greek ἁψίς (hapsís) 'arch, vault'; pl. apsides / ˈ æ p s ɪ ˌ d iː z / AP-sih-deez) [1] [2] is the farthest or nearest point in the orbit of a planetary body about its primary body.
Earth's Moon will occult Neptune. 2209 Perihelion of Comet Halley. Previous perihelion passages were in 1986, 2061, and 2134. 2221 May 27 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).
