Information: - 2101 Adonis was one of the first near - Earth asteroids to be discovered . It was discovered by Eugene Joseph Delporte in 1936 and named after Adonis , the beautiful youth with whom the goddess Venus fell in love . 2101 Adonis is believed to measure approximately 1 km in diameter . In the close approach of February 1936 that led to its initial discovery , the asteroid was observed for two months , but not enough observations could be made to calculate an orbit , and Adonis was a lost asteroid until 1977 when it was rediscovered by Charles T. Kowal . Adonis was the second Apollo asteroid to be discovered ( after 1862 Apollo itself ) . It may be an extinct comet , and may be the source of some meteor showers . 2101 Adonis 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 . The Earth - MOID is 0.0117 AU ( 1,750,000 km ; 1,090,000 mi ) . Its orbit is well - determined for the next several hundred years . Adonis makes close approaches to Venus , Earth , and Mars . It comes within 30 Gm of the Earth six times in the 21st century , the nearest being 0.03569 AU ( 5,339,000 km ; 3,318,000 mi ) on 7 February 2036 . - 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 (> 1 AU) but perihelion distances less than the Earth's aphelion distance (q < 1.017 AU). - A planet is an astronomical body orbiting a star or stellar remnant that The term "planet" is ancient, with ties to history, astrology, science, mythology, and religion. Several planets in the Solar System can be seen with the naked eye. These were regarded by many early cultures as divine, or as emissaries of deities. As scientific knowledge advanced, human perception of the planets changed, incorporating a number of disparate objects. In 2006, the International Astronomical Union (IAU) officially adopted a resolution defining planets within the Solar System. This definition is controversial because it excludes many objects of planetary mass based on where or what they orbit. Although eight of the planetary bodies discovered before 1950 remain "planets" under the modern definition, some celestial bodies, such as Ceres, Pallas, Juno and Vesta (each an object in the solar asteroid belt), and Pluto (the first trans-Neptunian object discovered), that were once considered planets by the scientific community, are no longer viewed as such. - Asteroids are minor planets, especially those of the inner Solar System. The larger ones have also been called planetoids. These terms have historically been applied to any astronomical object orbiting the Sun that did not show the disc of a planet and was not observed to have the characteristics of an active comet. As minor planets in the outer Solar System were discovered and found to have volatile-based surfaces that resemble those of comets, they were often distinguished from asteroids of the asteroid belt. In this article, the term "asteroid" refers to the minor planets of the inner Solar System including those co-orbital with Jupiter. - The asteroid belt is the circumstellar disc in the Solar System located roughly between the orbits of the planets Mars and Jupiter. It is occupied by numerous irregularly shaped bodies called asteroids or minor planets. The asteroid belt is also termed the main asteroid belt or main belt to distinguish it from other asteroid populations in the Solar System such as near-Earth asteroids and trojan asteroids. About half the mass of the belt is contained in the four largest asteroids: Ceres, Vesta, Pallas, and Hygiea. The total mass of the asteroid belt is approximately 4% that of the Moon, or 22% that of Pluto, and roughly twice that of Pluto's moon Charon (whose diameter is 1200km). Given the information, choose the subject and object entities that have the relation of 'minor planet group'.
