The asteroid belt is a torus-shaped region in the Solar System, centered on the Sun and roughly spanning the space between the orbits of the planets Jupiter and Mars. It contains a great many solid, irregularly shaped bodies called asteroids or minor planets .
[16] [17] [18] An astronomical unit, or AU, is the distance from Earth to the Sun, which is approximately 150 billion meters (93 million miles). [19] Small Solar System objects are classified by their orbits: [20] [21] Main Asteroid belt (main belt), between Mars and Jupiter, in near circular orbit, 2.2 to 3.2 AU
Preliminary analysis of this asteroid suggests it is a stony S-type or L-type asteroid with a rotation period near 19.5 minutes. [7] The asteroid previously made a close approach of 828,800 kilometres (515,000 miles; 2.156 lunar distances) to Earth on 25 December 2024 (two days before its discovery), and is now moving away from Earth.
outer main-belt (a > 2.82 AU Asteroid groups out to the orbit of Jupiter. The asteroid belt is shown in red. The overwhelming majority of known asteroids have orbits lying between the orbits of Mars and Jupiter, roughly between 2 and 4 AU. These could not form a planet due to the gravitational influence of Jupiter.
Fig 1: The Hildas Triangle against a background of all known asteroids up to Jupiter's orbit. Fig 2: The positions of the Hildas against a background of their orbits. The asteroids of the Hilda group (Hildas) are in 3:2 mean-motion resonance with Jupiter. [4] That is, their orbital periods are 2/3 that of Jupiter. They move along the orbits ...
In 2016, astronomers spotted an asteroid about the size of a ferris wheel in an Earth-like orbit around the Sun. Turns out it's actually a chunk of the moon.
The Lucy spacecraft zoomed by the small asteroid Dinkinesh, located in our solar system’s main asteroid belt between the orbits of Mars and Jupiter. But what astronomers thought was one asteroid ...
