In 2006, and after much debate, the International Astronomical Union came up with a new definition for a planet. And for the first time, the term "dwarf planet" was used.
Haumea is roughly about the same size as Pluto but its shape is highly irregular. N.A.S.A Plutoids A sub-section of dwarf planets was created by the I.A.U. in August 2006. All the dwarf planets except Ceres are member of this sub-group. For them to be a member of the group, ...
Dwarf Planetsare just as suitable as larger stars to support life. For a Sun-sized star, the planet would need to be about the same distance asEarthis to the Sun for it to support life. If the star is smaller, the planet would need to be nearer the star for the planet to be hot...
根据最后一段中 “Additionally, dwarf stars are dim, so the habitable zone lies closer in. If the planet is closer to the star, it's easier for astronomers to detect a transit observation. A close-in planet also has a stronger pull on its star. That makes it easier to detect with the...

It now shares its dwarf planet designation with three of the 1,200 bodies that have been located beyond Neptune today, collectively known as “Kuiper Belt Objects”. The Kuiper Belt is populated by icy bodies that are remnants of the solar system's formation. These are the building blocks ...

The word planet means ‘wanderer’. A planet is a large celestial body that revolves around the sun in fixed orbits. To learn more about planets visit BYJU'S
(Eris) or an Extrasolar planet. An extrasolar planet is a planet that orbits a star other than our Sun. Again, an extrasolar planet can be either Rocky, Gas or Dwarf. We have been discovering planets orbiting around other stars. Still, most of those have been Gas Giants whose lives ...
Eris' atmosphere is too thin to be considered a true atmosphere and appears primarily to be composed of methane that sublimates from ice on the... Learn more about this topic: Dwarf Planets in the Solar System | Overview & Composition ...
