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 .
Phaeton (alternatively Phaethon / ˈ f eɪ. ə θ ən / or Phaëton / ˈ f eɪ. ə t ən /; from Ancient Greek: Φαέθων, romanized: Phaéthōn, pronounced [pʰa.é.tʰɔːn]) is a hypothetical planet hypothesized by the Titius–Bode law to have existed between the orbits of Mars and Jupiter, the destruction of which supposedly led to the formation of the asteroid belt (including the ...
Main Asteroid belt (main belt), between Mars and Jupiter, in near circular orbit, 2.2 to 3.2 AU Hungaria asteroids, small group, 1.78 to 2.00 AU; Alinda asteroids, small group, 2.5 AU in elliptical orbits; Hilda asteroid small group just inside Jupiter, 4.0 AU; Kuiper belt large belt, 43 to 64.5 AU; Scattered disc small group, 21.5 to 215 AU
The European Southern Observatory’s Very Large Telescope images 42 asteroids, most larger than 100 kilometres in size.
Ceres (minor-planet designation: 1 Ceres) is a dwarf planet in the middle main asteroid belt between the orbits of Mars and Jupiter.It was the first known asteroid, discovered on 1 January 1801 by Giuseppe Piazzi at Palermo Astronomical Observatory in Sicily, and announced as a new planet.
Fifth planet (hypothetical), historical speculation about a planet between the orbits of Mars and Jupiter. Phaeton, a planet situated between the orbits of Mars and Jupiter whose destruction supposedly led to the formation of the asteroid belt. This hypothesis is now considered unlikely, since the asteroid belt has far too little mass to have ...
Look up to the sky Wednesday morning and you'll see what astronomers call a planetary conjunction as Jupiter and Mars appear to be close together.
The closest in the past 1,000 years was in 1761, when Mars and Jupiter appeared to the naked eye as a single bright object, according to Giorgini. Looking ahead, the year 2348 will be almost as close.
