What planet is considered the dwarf planet?

Answer 1

Dwarf planets are objects in our solar system that are big enough to pull themselves into a rounded shape yet orbit the Sun in a "messy" neighbourhood (like the asteroid belt, or the Kuiper Belt beyond Neptune.) So far, the International Astronomical Union lists five dwarf planets: Ceres in the asteroid belt, and Pluto, Haumea, Makemake and Eris in the Kuiper Belt. However, it is highly likely that a LOT more objects out there in the Kuiper Belt are round and therefore dwarf planets - we just haven't been able to observe them closely enough to prove it. It's likely that by the time we have better pictures of everything we've discovered so far we'll have found dozens, perhaps even hundreds of dwarf planets out there. Some examples of things that are almost certainly dwarf planets but that the IAU doesn't list yet as their shape isn't proven are Ixion, Orcus, Varuna, Quaoar and Sedna. So bear in mind that any list of dwarf planets is bound to grow quickly and will be out of date soon!

If you believe dwarf planets are planets, you can remember the five dwarf planets in order from the sun with the mnemonic: "Can Planets Have Massive Eccentricity?"

If you don't believe dwarf planets are planets and that only the eight big ones count, you can use this one: "Counting Planets Here Means Eight!"

And if you want to remember the five dwarf planets alongside the eight other planets, use "My Very Easy Method Can't Just Speed Up Naming Planets, However Many Exist!"

Answer 2

This is a rather vague question because there are many dwarf planets in the universe. It is a classification and there isn't one specific dwarf planet in the universe. However, that being said... Pluto. Pluto was discovered on February 18, 1930. From its discovery until 2006 it was considered a planet of our solar system. On August 24, 2006 the International Astronomical Union redefined what it "means to be planet" and reclassified Pluto as a dwarf planet.

Answer 3

five dwarf planets are recognised by the IAU;

Ceres (in the asteroid belt between Mars and Jupiter), Pluto, Haumea, Makemake and Eris.

Answer 4

Pluto is considered a dwarf planet. It is the largest known dwarf planet in our solar system and was reclassified from a full planet to a dwarf planet in 2006 by the International Astronomical Union.

Answer 5

Pluto is known as the dwarf planet.
