  2. List of Solar System objects by size - Wikipedia

    en.wikipedia.org/wiki/List_of_Solar_System...

    Currently most of the objects of mass between 10 9 kg to 10 12 kg (less than 1000 teragrams (Tg)) listed here are near-Earth asteroids (NEAs). The Aten asteroid 1994 WR12 has less mass than the Great Pyramid of Giza, 5.9 × 10 9 kg. For more about very small objects in the Solar System, see meteoroid, micrometeoroid, cosmic dust, and ...

  3. List of trans-Neptunian objects - Wikipedia

    en.wikipedia.org/wiki/List_of_trans-Neptunian...

    This list includes all numbered trans-Neptunian objects with a semi-major axis greater than 30.1 astronomical units (AU), Neptune's average orbital distance from the Sun. The data is sourced from MPC's "List of Trans Neptunian Objects" and "List Of Centaurs and Scattered-Disk Objects", completed with remarks and information from Johnston's Archive (diameter, class, binary, albedo, spectral ...

    Giant planet. The four giant planets of the Solar System: ( top) Jupiter and Saturn ( gas giants) ( bottom) Uranus and Neptune ( ice giants) Shown in order from the Sun and in true color. Sizes are not to scale. A giant planet, sometimes referred to as a jovian planet ( Jove being another name for the Roman god Jupiter ), is a diverse type of ...

    If the Sun–Neptune distance is scaled to 100 meters (330 ft), then the Sun would be about 3 cm (1.2 in) in diameter (roughly two-thirds the diameter of a golf ball), the giant planets would be all smaller than about 3 mm (0.12 in), and Earth's diameter along with that of the other terrestrial planets would be smaller than a flea (0.3 mm or 0. ...

    a dwarf planet, the third-largest-known trans-Neptunian object. Notable for its two known satellites, rings, and unusually short rotation period (3.9 h). It is the most massive known member of the Haumea collisional family. [28] [29] 136472 Makemake: a dwarf planet, a cubewano, and the fourth-largest known trans-Neptunian object [30] 136199 Eris

  7. List of gravitationally rounded objects of the Solar System

    en.wikipedia.org/wiki/List_of_gravitationally...

    Vesta (radius 262.7 ± 0.1 km), the second-largest asteroid, appears to have a differentiated interior and therefore likely was once a dwarf planet, but it is no longer very round today. [74] Pallas (radius 255.5 ± 2 km ), the third-largest asteroid, appears never to have completed differentiation and likewise has an irregular shape.

  8. List of Solar System objects - Wikipedia

    en.wikipedia.org/wiki/List_of_Solar_System_objects

    The following is a list of Solar System objects by orbit, ordered by increasing distance from the Sun. Most named objects in this list have a diameter of 500 km or more. The Sun, a spectral class G2V main-sequence star. The inner Solar System and the terrestrial planets. Mercury. Mercury-crossing minor planets. Venus. Venus-crossing minor planets.

  9. Kuiper belt - Wikipedia

    en.wikipedia.org/wiki/Kuiper_belt

    Between the 2:3 and 1:2 resonances with Neptune, at approximately 42–48 AU, the gravitational interactions with Neptune occur over an extended timescale, and objects can exist with their orbits essentially unaltered. This region is known as the classical Kuiper belt, and its members comprise roughly two thirds of KBOs observed to date.
