Astronomers have deduced from a meteorite that the second largest asteroid in the Asteroid Belt was part of a tremendous collision

While typical accretion models generate good analogues to Earth and Venus, they predict that Mars should be of similar size, or even larger than Earth. Additionally, these models also overestimate the overall mass of the asteroid belt.

An impact crater on Earth can be traced back to the asteroid belt object Vesta.

2016年10月26日 · Meteorite Jewellery. Yes, you heard that right. We’re here to discuss actual, genuine, real meteorite jewellery with real meteorites.

Astronomers have created the first detailed image that shows the true nature of the surface of Antares, producing the first-ever map of the red supergiant’s atmosphere. The gaseous envelope of Antares, which would extend further than the Asteroid Belt if it were placed in our Solar System, has shown to experience unexpected turbulence.

2017年4月14日 · The new ALMA data reveal, for the first time, that DeeDee is roughly 635 kilometres (395 miles) across, or about two-thirds the diameter of the dwarf planet Ceres, the largest member of our asteroid belt.

The planet orbits roughly 300 million miles from the stellar duo, about the distance from the asteroid belt to our Sun. It completes an orbit around both stars roughly every seven years. The two red dwarf stars are a mere 7 million miles apart, …

A new statistical study of planets found by a technique called gravitational microlensing suggests that Neptune-mass worlds are likely the most common type of planet to form in the icy outer realms of planetary systems.

2018年11月20日 · It is the largest object in an asteroid class known as Centaurs, according to NASA. Meanwhile, Haumea, a trans-Neptunian object, about the size of Pluto, looks like a flattened ball with a 620 kilometre (385-mile) diameter. It is found in the Kuiper Belt, a region beyond the orbit of Neptune.

Data from the Dawn spacecraft suggests the world’s interior is the source, as opposed to arriving via impacting asteroids or comets
