What is the 2 dwarf planet?
These five bodies – the three under consideration in 2006 (Pluto, Ceres and Eris) plus the two named in 2008 (Haumea and Makemake) – are commonly presented as the dwarf planets of the Solar System, though the limiting factor (albedo) is not what defines an object as a dwarf planet.

Pluto is a dwarf planet that lies in the Kuiper Belt, an area full of icy bodies and other dwarf planets out past Neptune. Pluto is very small, only about half the width of the United States and its biggest moon Charon is about half the size of Pluto.
Is Jupiter a dwarf planet?
Following the laws of Kepler, Jupiter and the Trojans have the same speed, so Jupiter can’t catch them and although Jupiter’s gravity is very strong, it does not stretch to the other side of the sun, which means, following the definition, that Jupiter is a dwarf planet.
Is Uranus a dwarf planet?

Is Neptune a dwarf planet?
Shouldn’t Neptune be considered a dwarf planet? Neptune is still considered a planet because its mass is much greater than the combined mass of everything else that crosses its orbit (including Pluto). Neptune is about 8000 times more massive than Pluto, so Neptune is a planet and Pluto is a dwarf planet.
Is Venus a dwarf planet?
For three-quarters of a century, schoolkids learned that our solar system has nine planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto.
How many dwarf planets are there in our Solar System?
The number of dwarf planets in the Solar System is unknown. Estimates have run as high as 200 in the Kuiper belt and over 10,000 in the region beyond. However, consideration of the surprisingly low densities of many dwarf-planet candidates suggests that the numbers may be much lower, possibly only nine among bodies known so far. The International Astronomical Union (IAU) required dwarf planets
Where do the dwarf planets fit into the Solar System?
The solar system’s erratic ninth planet, Pluto, was assigned to the new “ dwarf planet ” category along with four other bodies, all tinier than Earth’s moon. Some astronomers expect there may be as many as 50 dwarf planets in the solar system. Eris, the largest dwarf planet, is only slightly bigger than Pluto, at 1,445 miles in diameter (2,326 km).
