The absolute magnitudes of most of the known asteroids are between 11 and 19, with the median at about 16. [67] On average the distance between the asteroids is about 965,600 km (600,000 miles), [68] [69] although this varies among asteroid families and
Most highly inclined known main-belt asteroid from August 30, 1935, to June 14, 1980 MPC: 1580 Betulia: 52.083° May 22, 1950 most highly inclined known minor planet from May 22, 1950, to July 4, 1973 MPC: 2938 Hopi: 41.436° June 14, 1980 Most highly inclined known main-belt asteroid from June 14, 1980, to September 20, 2000 MPC (5496) 1973 NA ...
core X-type containing the asteroids with the most "typical" spectra; Xe-type of asteroids whose spectra contain a moderately broad absorption band around 0.49 μm. It has been suggested that this indicates the presence of troilite (FeS). There is some correlation between this group and the Tholen E-type.
Asteroids are classified by their characteristic emission spectra, with the majority falling into three main groups: C-type, M-type, and S-type. These describe carbonaceous (carbon-rich), metallic, and silicaceous (stony) compositions, respectively. The physical composition of asteroids is varied and in most cases poorly understood.
Ryugu belongs to a class of asteroids called carbonaceous, or C-type, asteroids. C-type asteroids are rich in water, carbon and organic compounds from when the solar system formed.
Here's what to know about Apophis and how space agencies hope to protect Earth from other asteroids like it. Apophis to make 2029 flyby to Earth Apophis is projected to pass within 20,000 miles of ...
The asteroid and comet belts orbit the Sun from the inner rocky planets into outer parts of the Solar System, interstellar space. [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]
Asteroid families become visible as distinct concentrations when asteroids are plotted in the proper orbital element space (i p vs a p).Some prominent families are the Vesta, Eunomia, Koronis, Eos, and Themis family located in different (colorized) regions of the asteroid belt.
