Apollo Asteroid
The Apollo asteroids are a group of near-Earth asteroids named after 1862 Apollo, discovered by German astronomer Karl Reinmuth in the 1930s. They are Earth-crossing asteroids that have an orbital semi-major axis greater than that of the Earth (a > 1 AU) but perihelion distances less than the Earth's aphelion distance (q < 1.017 AU). , the number of known Apollo asteroids is 10,485, making the class the largest group of s (''cf''. the , Amor and Atira asteroids), [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1862 Apollo
1862 Apollo is a stony asteroid, approximately 1.5 kilometers in diameter, classified as a near-Earth object (NEO). It was discovered by German astronomer Karl Reinmuth at Heidelberg Observatory on 24 April 1932, but lost and not recovered until 1973. It is the namesake and the first recognized member of the Apollo asteroids, a subgroup of NEOs which are Earth-crossers, that is, they cross the orbit of the Earth when viewed perpendicularly to the ecliptic plane (crossing an orbit is a more general term than actually intersecting it). 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. 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.

1866 Sisyphus
1866 Sisyphus is a binary stony asteroid, near-Earth object and the largest member of the Apollo group, approximately 7 kilometers in diameter. It was discovered on 5 December 1972, by Swiss astronomer Paul Wild at Zimmerwald Observatory near Bern, Switzerland, and given the provisional designation . It was named after Sisyphus from Greek mythology. Orbit and classification This S-type asteroid (composed of rocky silicates) orbits the Sun in the inner main-belt at a distance of 0.9–2.9 AU once every 2 years and 7 months (952 days). Its orbit has an eccentricity of 0.54 and an inclination of 41 ° with respect to the ecliptic. The Apollo asteroid has an ''Earth minimum orbit intersection distance'' of , which corresponds to 40.4 lunar distances. It will pass from Earth on 24 November 2071, and will peak at roughly apparent magnitude 9.3 on 26 November 2071. When it was discovered it peaked at magnitude 9.0 on 25 November 1972. It is one of the brightest near-Earth a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2008 TC3
(Catalina Sky Survey temporary designation 8TA9D69) was an , diameter asteroid that entered Earth's atmosphere on October 7, 2008. It exploded at an estimated above the Nubian Desert in Sudan. Some 600 meteorites, weighing a total of , were recovered; many of these belonged to a rare type known as ureilites, which contain, among other minerals, nanodiamonds. It was the first time that an asteroid impact had been predicted before its entry into the atmosphere as a meteor. Discovery The asteroid was discovered by Richard A. Kowalski at the Catalina Sky Survey (CSS) 1.5-meter telescope at Mount Lemmon, north of Tucson, Arizona, US, on October 6, 06:39 UTC, 19 hours before the impact. It was notable as the first such body to be observed and tracked prior to reaching Earth. The process of detecting and tracking a near-Earth object, an effort sometimes referred to as Spaceguard, was put to the test. In total, 586 astrometric and almost as many photometric observations w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2003 SQ222
3 (three) is a number, numeral and digit. It is the natural number following 2 and preceding 4, and is the smallest odd prime number and the only prime preceding a square number. It has religious or cultural significance in many societies. Evolution of the Arabic digit The use of three lines to denote the number 3 occurred in many writing systems, including some (like Roman and Chinese numerals) that are still in use. That was also the original representation of 3 in the Brahmic (Indian) numerical notation, its earliest forms aligned vertically. However, during the Gupta Empire the sign was modified by the addition of a curve on each line. The Nāgarī script rotated the lines clockwise, so they appeared horizontally, and ended each line with a short downward stroke on the right. In cursive script, the three strokes were eventually connected to form a glyph resembling a with an additional stroke at the bottom: ३. The Indian digits spread to the Caliphate in the 9th ...

2004 FN8
4 (four) is a number, numeral and digit. It is the natural number following 3 and preceding 5. It is the smallest semiprime and composite number, and is considered unlucky in many East Asian cultures. In mathematics Four is the smallest composite number, its proper divisors being and . Four is the sum and product of two with itself: 2 + 2 = 4 = 2 x 2, the only number b such that a + a = b = a x a, which also makes four the smallest squared prime number p^. In Knuth's up-arrow notation, , and so forth, for any number of up arrows. By consequence, four is the only square one more than a prime number, specifically three. The sum of the first four prime numbers two + three + five + seven is the only sum of four consecutive prime numbers that yields an odd prime number, seventeen, which is the fourth super-prime. Four lies between the first proper pair of twin primes, three and five, which are the first two Fermat primes, like seventeen, which is the third. On the other hand, t ...

1991 VG
1991 VG is a very small near-Earth object of the Apollo group, approximately in diameter. It was first observed by American astronomer James Scotti on 6 November 1991, using the Spacewatch telescope on Kitt Peak National Observatory near Tucson, Arizona, in the United States. On 6 December 1991 it passed about from the Moon. The asteroid then went unobserved from April 1992 until it was recovered by Paranal Observatory in May 2017. It was removed from the Sentry Risk Table on 1 June 2017. Earth-like orbit On 6 November 1991, Scotti discovered a faint object which was designated ''1991 VG'' soon after discovery. The object's heliocentric orbit was found to be very similar to Earth's orbit and it was calculated that it would make a close approach to Earth in the month after discovery at 1.2 lunar distances or on 5 December 1991. ''1991 VG'' also passed 0.0568 AU from Earth on 7 August 2017 and 0.0472 au on 11 February 2018. Given such an Earth-like orbit, the dyn ...

1999 XS35

Its orbital eccentricity is 0.94, which means that at the Apsis, perihelion comes as close as 0.9 AU to the Sun, while at the Apsis, aphelion it reaches beyond the orbit of Neptune. is a damocloid. is a small object with an Absolute magnitude#Solar System bodies (H), absolute magnitude (H) of 17.2, which implies a size of about 1 km. came to perihelion on 21 October 1999, passed from Earth on 5 November 1999, and was discovered on 2 December 1999 at about apparent magnitude 16.9.

(5496) 1973 NA
(5496) 1973 NA, is a very eccentric and heavily tilted asteroid, classified as near-Earth object of the Apollo group, approximately 2 kilometers in diameter. It was discovered on 4 July 1973, by American astronomer Eleanor Helin at the U.S. Palomar Observatory in California. At the time of its discovery, it was the most highly inclined minor planet known to exist. It may be the parent body of the Quadrantids. Parent of the Quadrantids is a possible parent body of the Quadrantids, a major meteor shower that occurs every January. It may also be just a fragment of the parent or the dormant remains of the parent. Other possible parent bodies are and comet 96P/Machholz, as well as . Orbit and classification The asteroid orbits the Sun at a distance of 0.9–4.0 AU once every 3 years and 10 months (1,388 days). Its orbit has an eccentricity of 0.64 and an inclination of 68 ° with respect to the ecliptic. No precoveries were taken. The asteroid's observation arc even beg ...
