Although Apollo was the first Apollo asteroid to be discovered, its official IAU-number (1862) is higher than that of some other Apollo asteroids such as 1566 Icarus, due to the fact that it was a lost asteroid for more than 40 years and other bodies were numbered in the meantime. Some of these asteroids can get very close to the Earth, making them a potential threat to our planet. Icarus, an Apollo asteroid (one that passes inside Earth’s orbit). Wall Street Journal. Read More NEAs are divided into groups (Atira, Aten, Apollo and Amor) according to their perihelion distance (q), aphelion distance (Q) and their semi-major axes (a). [7] The satellite is only 80 m (260 ft) across and orbits Apollo just 3 km (1.9 mi) away from the asteroid itself. 1862 Apollo / ə ˈ p ɒ l oʊ / is a stony asteroid, approximately 1.5 kilometers in diameter, classified as a near-Earth object (NEO).
Apollo asteroids cross Earth’s orbit so they are of particular interest. [a], 1862 Apollo is a potentially hazardous asteroid (PHA) because its minimum orbit intersection distance (MOID) is less than 0.05 AU and its diameter is greater than 150 meters.
[5], It is named after the Greek god Apollo. It was discovered on June 27, 1949, by German-born American astronomer Walter Baade of the Hale Observatories (now Palomar Observatory), California. This page was last changed on 6 May 2014, at 15:22.
It was discovered by German astronomer Karl Reinmuth at Heidelberg Observatory on 24 April 1932, but lost and not recovered until 1973.
[8] From the surface of Apollo, S/2005 (1862) 1 would have an angular diameter of about 2.0835 degrees. At the time of its discovery, Icarus had a more-eccentric orbit than any other The analysis of its rotation provided observational evidence of the YORP effect. The mean distances of Apollo asteroids from the Sun are greater than or equal to 1 AU, and their perihelion distances are less than…. The announcement is contained in the International Astronomical Union Circular (IAUC) 8627. The Apollo asteroids are a group of asteroids near Earth named after 1862 Apollo, the first asteroid of this group to be discovered by Karl Wilhelm Reinmuth. due to just miss. By signing up for this email, you are agreeing to news, offers, and information from Encyclopaedia Britannica. In addition, since Apollo's orbit is highly eccentric, it crosses the orbits of Venus and Mars and is therefore called a Venus-crosser and Mars-crosser as well. Some of these asteroids can get very close to the Earth, making them a potential threat to our planet. October 07, 2020. Apollo's Earth MOID is 0.0257 AU (3,840,000 km; 2,390,000 mi). Potentially Hazardous Asteroids (PHAs) are currently defined based on parameters that measure the asteroid's potential … Apollo asteroid.

[1] Its orbit is well-determined for the next several hundred years. …to be discovered were the Apollo asteroids, named for (1862) Apollo, which was discovered in 1932 but was lost shortly thereafter and not rediscovered until 1978. Apollo asteroids Earth (E) As of December 2018 [update] the number of known Apollo asteroids is 10,485, making the class the largest group of near-Earth objects ( cf .
Earth on. Apollo Asteroid. He is the god of the Sun, child of Zeus and Leto, after which the minor planets 5731 Zeus and 68 Leto are named.
