Mar 12, 2025 · Our solar system has five dwarf planets: In order of distance from the Sun they are: Ceres, Pluto, Haumea, Makemake, and Eris.

a short video of the rotation of the dwarf planets and some dwarf planet candidates. A dwarf planet is a small planetary-mass object that is in direct orbit around the Sun, massive enough to be gravitationally rounded, but insufficient to achieve orbital dominance like the eight classical planets of the Solar System.

Smaller trans-Neptunian objects have been called dwarf planets if they appear to be solid bodies, which is a prerequisite for hydrostatic equilibrium: planetologists generally include at least Gonggong, Orcus, and Sedna. Quaoar was stated as a dwarf planet under a 2022–2023 annual report, though it does not appear to be in hydrostatic ...

According to the International Astronomical Union (IAU), there are 8 planets and 5 officially recognized dwarf planets in our solar system. These 8 planets are “Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune”.

Apr 19, 2023 · The IAU currently recognizes five dwarf planets: Ceres, Pluto, Haumea, Makemake, and Eris. Ceres lies in the main asteroid belt between Mars and Jupiter, while the rest are in the Kuiper Belt. There are almost certainly more dwarf planets. Unfortunately, most are very far away, and we can’t definitively prove that they are round.

Oct 28, 2017 · Dwarf planets are worlds too small to be full-fledged planets, but too big to fit in smaller astronomical categories. Pluto, the most famous dwarf planet, lost its planet status in 2006.

6 days ago · Dwarf planet, body, other than a natural satellite (moon), that orbits the Sun and that is, for practical purposes, smaller than the planet Mercury yet large enough for its own gravity to have rounded its shape substantially.

Nov 10, 2022 · The dwarf planet classification has existed only since 2006 and its exact definition is still a work in progress. The main differences between a planet and a dwarf planet are orbital dominance and hydrostatic equilibrium. Dwarf planets are considerably smaller than planets.

There are currently only five official dwarf planets namely, Ceres, Pluto, Haumea, Makemake, and Eris. However, there are many other dwarf planet candidates like Gonggong, Orcus, Quaoar, Sedna, and Salacia. The dwarf planets were named after mythological characters.

Aug 10, 2024 · Five officially recognized dwarf planets exist in our solar system: Ceres, Pluto, Haumea, Makemake, and Eris. Pluto is the largest dwarf planet with a diameter of approximately 2,374 kilometers. Eris is the farthest dwarf planet from the Sun, orbiting at an average distance of 96 astronomical units.
