What planets have Trojan asteroids?

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.

Does the earth have any Trojan asteroids?

An Earth trojan is an asteroid that orbits the Sun in the vicinity of the Earth–Sun Lagrangian points L4 (leading 60°) or L5 (trailing 60°), thus having an orbit similar to Earth’s. Only two Earth trojans have so far been discovered.

Where are the Trojans asteroids located?

The Trojan asteroids are located at the Lagrangian points, L4 and L5, located 60o in front of and behind Jupiter respectively. Due to perturbations by the other planets, their distributions are elongated along the orbit. There are currently over 4,800 known Trojan asteroids associated with Jupiter.

Does Saturn have Trojan asteroids?

WHERE ARE THE SATURN TROJANS? asteroids have been found around the libration points of Uranus and Saturn. With the aid of numerical integrations we checked the stability of fictitious bodies in the 1:1 Mean Motion Resonance with Saturn. Even the Earth has one Trojan close to L4 (Connors et al, 2011).

Who discovered Trojan planets?

Trojan Planets. In 1772 the French mathematician and astronomer Joseph-Louis Lagrange predicted the existence and location of two groups of asteroids located near the (L4 and L5) equilateral triangular stability points of a three-body system formed by the Sun, Jupiter, and the asteroids.

What is the name of Earth’s Trojan?

Earth’s confirmed trojan, named 2010 TK7, is a chunk of rock around 300 metres (984 feet) across, hanging about the Earth-leading L4 Lagrangian in an oscillating tadpole-shaped orbit known as libration.

Why are there no Saturn Trojans?

The answer is complex but likely relates to the properties of (near-)resonances in the Solar System, which can stabilise or destabilise orbits at quite a long range. As noted in James K’s answer, perturbations from Jupiter are the main reason for the absence of Saturnian Trojans.

Does Mercury have Trojan asteroids?

Mercury trojans, asteroids trapped in Mercury’s Lagrange points, are also possible.

How many asteroids did Trojan have?

As of 2020, of the more than 7,000 Jupiter Trojan asteroids discovered, about two-thirds are located near L4, and the remainder are near L5. Astronomers estimate that 1,800–2,200 of the total existing population of Jupiter’s Trojans have diameters greater than 15 km (10 miles).

Does Mercury have any Trojans?

Are there any Trojan asteroids that orbit other planets?

There are Trojans orbiting Venus, Earth, Mars, Jupiter, Uranus, and Neptune. Trojan asteroids were suspected to exist as far back as 1772 but weren’t observed for some time. The mathematical justification for the existence of Trojan asteroids was developed in 1772 by Joseph-Louis Lagrange.

Is there water on Jupiter trojans?

Most Jupiter Trojans are D-class asteroids, which predominate in the outer regions of the asteroid belt. Very few have been classified as P or C-type asteroids. Water hasn’t yet been detected on any of them; however, there is a possibility that some of them might contain it.

Is there a trojan planet on the Earth?

The first known Earth Trojan was confirmed in 2011. It lies ahead of Earth in the L4 point and was designated 2010 TK 7. Venus is known to have a temporary Trojan, designated as 2013 ND 15. The large asteroid-dwarf-planet Ceres and the asteroid Vesta also have temporary Trojans.

Where do asteroids orbit the Sun?

While the majority of the asteroids in our solar system seem to orbit in the Asteroid Belt, there are other groups that orbit the Sun at various distances in both the inner and outer solar system. Among these are the so-called Trojan Asteroids, which are individually named after figures in the legendary Trojan Wars from Greek myths.
