Trojan Asteroids
Related Category: Astronomy: General
two groups of asteroids that revolve about the sun in the same orbit as Jupiter; one group is about 60° ahead of the planet in the orbit, the other about 60° behind it.

Trojan asteroids
In 1772 the French mathematician and astronomer Joseph-Louis Lagrange predicted the existence and location of two groups of small bodies located near a pair of gravitationally stable points along Jupiter’s orbit.
Trojan asteroids One of two groups of asteroids which orbit at the same distance from the Sun as Jupiter, 60 degrees ahead and behind the planet.

Trojan Asteroids
As of 2005, there are two known Trojan asteroids of Neptune which have the same orbital period as the planet. They lie in the elongated, curved regions around the L4 and L5 Lagrangian points 60° ahead of and behind Neptune.

TROJAN ASTEROIDS
Trojan asteroids are that orbit in gravitationally stable in a planet's orbit, either trailing it or preceding it (these places are where the gravitational attraction of the Sun and of the planet balance each other).

The Trojan asteroids are two families of asteroids stationed at the Lagrangian points in Jupiter's orbit. The first one discovered was 588 Achilles but the largest is 624 Hektor.

The so-called Trojan asteroids lie in two clouds, one moving 60° ahead of Jupiter in its orbit and the other 60° behind. In 1977 the asteroid Chiron was discovered in an orbit between that of Jupiter and Saturn.
Trojan asteroids (NASA SP-7, 1965) Two groups of minor planets that liberate in long-period orbits around the stable Lagrangian points of the Sun and Jupiter. Called Trojan because they are named after hereos of the Trojan War.
Mars has one known co-orbital asteroid (5261 Eureka), and Jupiter has many (about 400 objects, the Trojan asteroids); there are also other small co-orbital moons in the Saturnian system: Telesto and Calypso with Tethys, ...
These may be captured asteroids, similar to 5261 Eureka, a Martian Trojan asteroid. Mars can be seen from Earth with the naked eye. Its apparent magnitude reaches âˆ'2.
Although Trojan asteroids have been discovered for Mars (5, all at L5) and Neptune (2), the term generally refers to the ~1800 asteroids accompanying Jupiter (~60% at L4).
In the Sun-Jupiter system several thousand asteroids, collectively referred to as Trojan asteroids, are in orbits around the Sun-Jupiter L4 and L5 points.
Because of the presence of other planets, principally Saturn, the Sun-Jupiter-Trojan asteroid system is not a true three-body system, and so these other three points are not stable and no asteroids have been found near them.

Trojan asteroids are located in either of Jupiter's L4 or L5 points, though the term is also sometimes used for asteroids in any other planetary Lagrange point as well.

The main asteroid belt is estimated to contain millions of objects and is located between the orbits of Mars and Jupiter. The Trojan asteroids are a separate group of asteroids lying outside the main asteroid belt and sharing an orbit with Jupiter.
There are also asteroids that lie in the Lagrange 4 and 5 points of some planets. These are called Trojan asteroids. Mars has 6 known, Jupiter has over 1619 known, and Neptune has 1 known.
Most are in the Asteroid Belt, which lies between Mars and Jupiter. Many more share the orbit of Jupiter; they are known as the Trojan Asteroids. Some are closer to the Sun than the Earth's orbit; these are known as the Aten Asteroids.
Sheppard has more discussion on Jupiter's "Trojan Asteroids, including a chart of the stable 60-degree Lagrange clouds of these objects (at the leading L4 and lagging L5 points in Jupiter's orbit around the Sun).

Several hundred of so-called Trojan Asteroids are located in the vicinity of Jupiter's L4 and L5 points, orbiting the Sun with the same period as Jupiter. They are known as "Trojan" because their names come from characters in Homer's Iliad.

These are the Trojan asteroids. They are in those locations because of Jupiter's strong pull on them.
The Trojan asteroids, named for heroes of the Trojan war, are in the orbit of Jupiter. astral dome = astrodome. astre fictif A point on the celestial sphere used as a reference in measuring time intervals. See day.
