An Earth trojan is an asteroid that orbits the Sun in the vicinity of the Earth–Sun Lagrange points L 4 (leading 60°) or L 5 (trailing 60°), thus having an orbit similar to Earth's. Only two Earth trojans have so far been discovered.
2010 TK 7 was confirmed to be the first known Earth trojan in 2011. It is located in the L 4 Lagrangian point, which lies ahead of the Earth. [14] (614689) 2020 XL 5 was found to be another Earth trojan in 2021. It is also at L4. [15] [16] (687170) 2011 QF 99 was identified as the first Uranus trojan in 2013. It is located at the L 4 Lagrangian ...
L 4 is the Sun–Earth Lagrange point located close to the Earth's orbit 60° ahead of Earth. Asteroid (706765) 2010 TK 7 is the first discovered tadpole orbit companion to Earth, orbiting L 4 ; like Earth, its mean distance to the Sun is about one astronomical unit .
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 L 4, existing 60° ahead of the planet in its orbit, or L 5, 60° behind.
Astronomers spotted a possible “sibling” planet that shares the orbit of another exoplanet in a system located 370 light-years away.
2010 TK 7 was at the near-Earth end of its tadpole in 2010–2011, [4] which facilitated its discovery. 2010 TK 7 's orbit has a chaotic character, making long-range predictions difficult. Prior to 500 AD, it may have been oscillating about the L 5 Lagrangian point (60 degrees behind Earth), before jumping to L 4 via L 3 .
The fossils were between 35.5 to 35.9 million years old and were found in a nearly 10-foot-long rock core: a tube-like sample taken from underneath the Gulf of Mexico by the scientific Deep Sea ...
Scientists using an ocean drilling vessel have dug the deepest hole ever in rock from Earth's mantle - penetrating 4,160 feet (1,268 meters) below the Atlantic seabed - and obtained a large sample ...
