  2. Asteroid belt - Wikipedia

    en.wikipedia.org/wiki/Asteroid_belt

    The total mass of the asteroid belt is significantly less than Pluto's, and roughly twice that of Pluto's moon Charon. 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.

  3. Solar System belts - Wikipedia

    en.wikipedia.org/wiki/Solar_System_belts

    Solar System belts are asteroid and comet belts that orbit the Sun in the Solar System in interplanetary space. [1] [2] The Solar System belts' size and placement are mostly a result of the Solar System having four giant planets: Jupiter, Saturn, Uranus and Neptune far from the sun. The giant planets must be in the correct place, not too close ...

  4. Asteroidal water - Wikipedia

    en.wikipedia.org/wiki/Asteroidal_water

    The formation of asteroidal water mirrors that of water formation in the Solar System, either from transfer via bombardment, migration, ejection, or other means. Asteroidal water has recently been pursued as a resource to support deep space exploration activities, for example, for use as a rocket propellant , human consumption, or for ...

    Another 8% of the Earth meteorites can be traced to the Flora and Nysa asteroid families in the main asteroid belt, the research found. And about 6% of the meteorites can be traced to Vesta, it ...

    [2] [21] [62] [66] In the Solar System they may be represented by Earth and Venus. [21] Formation of both planets required merging of approximately 10–20 embryos, while an equal number of them were thrown out of the Solar System. [62] Some of the embryos, which originated in the asteroid belt, are thought to have brought water to Earth. [64]

    en.wikipedia.org/wiki/Solar_System

    The asteroid belt contains tens of thousands, possibly millions, of objects over one kilometer in diameter. [141] Despite this, the total mass of the asteroid belt is unlikely to be more than a thousandth of that of Earth. [40] The asteroid belt is very sparsely populated; spacecraft routinely pass through without incident. [142]

    The asteroid responsible for our last mass extinction 66 million years ago — wiping out the dinosaurs — originated from the far reaches of our solar system, unlike most asteroids that have ...

  9. Grand tack hypothesis - Wikipedia

    en.wikipedia.org/wiki/Grand_Tack_Hypothesis

    Jupiter's migration across the asteroid belt increases the eccentricities and inclinations of the asteroids, resulting in a 0.5 Myr period of impact velocities sufficient to vaporize metals. If the formation of CB chondrites was due to Jupiter's migration it would have occurred 4.5-5 Myrs after the formation of the Solar System. [29]
