Ceres(minor-planet designation: 1 Ceres) is a dwarf planetin the middle main asteroid beltbetween the orbits of Marsand Jupiter. It was the first known asteroid, discovered on 1 January 1801 by Giuseppe Piazziat Palermo Astronomical Observatoryin Sicily, and announced as a new planet.
The asteroid belt is the smallest and innermost known circumstellar disc in the Solar System. Classes of small Solar System bodies in other regions are the near-Earth objects, the centaurs, the Kuiper belt objects, the scattered disc objects, the sednoids, and the Oort cloud objects. About 60% of the main belt mass is contained in the four ...
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 ...
541132 Leleākūhonua (/ ˌ l ɛ l eɪ ɑː ˌ k uː h oʊ ˈ n uː ə /) (provisional designation 2015 TG 387) is an extreme trans-Neptunian object and sednoid in the outermost part of the Solar System. It was first observed on 13 October 2015, by astronomers at the Mauna Kea Observatories, Hawaii.

The Sun in true white color. The Sun is the Solar System's star and by far its most massive component. Its large mass (332,900 Earth masses), [74] which comprises 99.86% of all the mass in the Solar System, [75] produces temperatures and densities in its core high enough to sustain nuclear fusion of hydrogen into helium.

3200 Phaethon ( / ˈfeɪ.əˌθɒn /; previously sometimes spelled Phaeton ), provisionally designated 1983 TB, is an active [8] Apollo asteroid with an orbit that brings it closer to the Sun than any other named asteroid (though there are numerous unnamed asteroids with smaller perihelia, such as (137924) 2000 BD 19 ).
