The Jupiter trojans, commonly called trojan asteroids or simply trojans, are a large group of asteroids that share the planet Jupiter's orbit around the Sun. Relative to Jupiter, each trojan librates around one of Jupiter's stable Lagrange points: either L4, existing 60° ahead of the planet in its orbit, or L5, 60° behind. Jupiter trojans are distributed in two elongated, curved regions around these Lagrangian points with an average semi-major axis of about 5.2 AU.
Eleanor Francis "Glo" Helin was an American astronomer. She was principal investigator of the Near-Earth Asteroid Tracking (NEAT) program of NASA's Jet Propulsion Laboratory.
David Clifford Jewitt is a British-American astronomer who studies the Solar System, especially its minor bodies. He is based at the University of California, Los Angeles, where he is a Member of the Institute for Geophysics and Planetary Physics, the Director of the Institute for Planets and Exoplanets, Professor of Astronomy in the Department of Physics and Astronomy and Professor of Astronomy in the Department of Earth, Planetary and Space Sciences. He is best known for being the first person to discover a body beyond Pluto and Charon in the Kuiper belt.
The Panoramic Survey Telescope and Rapid Response System located at Haleakala Observatory, Hawaii, US, consists of astronomical cameras, telescopes and a computing facility that is surveying the sky for moving or variable objects on a continual basis, and also producing accurate astrometry and photometry of already-detected objects. In January 2019 the second Pan-STARRS data release was announced. At 1.6 petabytes, it is the largest volume of astronomical data ever released.
Wide-field Infrared Survey Explorer is a NASA infrared astronomy space telescope in the Explorers Program launched in December 2009. WISE discovered thousands of minor planets and numerous star clusters. Its observations also supported the discovery of the first Y-type brown dwarf and Earth trojan asteroid. WISE performed an all-sky astronomical survey with images in 3.4, 4.6, 12 and 22 μm wavelength range bands, over ten months using a 40 cm (16 in) diameter infrared telescope in Earth orbit.
4007 Euryalos is a larger Jupiter trojan from the Greek camp, approximately 48 kilometers in diameter. It was discovered on 19 September 1973, by Dutch astronomers Ingrid and Cornelis van Houten at Leiden, and Tom Gehrels at Palomar Observatory in California. The likely spherical Jovian asteroid is the principal body of the proposed Euryalos family and has a rotation period of 6.4 hours. It was named after the warrior Euryalus from Greek mythology.
3793 Leonteus is a large Jupiter trojan from the Greek camp, approximately 90 kilometers in diameter. It was discovered on 11 October 1985, by American astronomer couple Carolyn and Eugene Shoemaker at the Palomar Observatory in California, United States. The D-type Jovian asteroid belongs to the 30 largest Jupiter trojans and has a rotation period of 5.6 hours. It was named after the hero Leonteus from Greek mythology.
9694 Lycomedes is a Jupiter trojan from the Greek camp, approximately 32 kilometers in diameter. It was discovered during the Palomar–Leiden survey at the Palomar Observatory in 1960 and later named after Lycomedes from Greek mythology. The dark Jovian asteroid is likely elongated in shape and has a rotation period of 18.2 hours.
13062 Podarkes is a mid-sized Jupiter trojan from the Greek camp, approximately 29 kilometers in diameter. It was discovered on 19 April 1991, by American astronomer couple Carolyn and Eugene Shoemaker at the Palomar Observatory, California. The dark Jovian asteroid is the principal body of the proposed Podarkes family. It was named after Podarkes from Greek mythology.
9142 Rhesus is a larger Jupiter trojan from the Trojan camp, approximately 42 kilometers in diameter. It was discovered during the third Palomar–Leiden Trojan survey in 1977, and later named after King Rhesus from Greek mythology. The dark D-type asteroid has a rotation period of 7.3 hours.
2010 TK7 is a sub-kilometer Near-Earth asteroid and the first Earth trojan discovered; it precedes Earth in its orbit around the Sun. Trojan objects are most easily conceived as orbiting at a Lagrangian point, a dynamically stable location (where the combined gravitational force acts through the Sun's and Earth's barycenter) 60 degrees ahead of or behind a massive orbiting body, in a type of 1:1 orbital resonance. In reality, they oscillate around such a point. Such objects had previously been observed in the orbits of Mars, Jupiter, Neptune, and the Saturnian moons Tethys and Dione.
