What makes a planet be classified as a dwarf planet instead of a moon?
Moons orbit planets. Planets (and dwarf planets) orbit stars.
What makes asteroids different from dwarf planets?
You can consider a dwarf planet to be a special case from an asteroid - one that has achieved hydrostatic equilibrium, which basically means that it has enough gravity to force it into a round shape.
Which planets has longer time of revolving arround the sun?
The time of revolving depends on the distance so that the more distant planets take longer to get round, and as well as that they move more slowly, which makes them take even longer. The record is held by the dwarf planet Sedna, which takes 11,400 years for one revolution of its highly elliptical orbit.
Why are dwarf planets small?
Dwarf planets are not a special type of planet. A small planet is later classified a dwarf planet. The only characteristic that makes it a dwarf planet is the size. Your question should be why are some planets small?
How much earth years makes 1 year on Sedna?
A year on Sedna is 10,500 Earth years.
What makes an asteroid different from a dwarf planet?
Generally it's the size. If an asteroid were to be big enough to achieve hydrostatic equilibrium (approximately spherical in shape), then it may be classed as a dwarf planet, such as Ceres. Asteroids are generally too small to active this shape under their gravity so are not classed as dwarf planets.
Why does the number of dwarf planets constantly change?
The number of dwarf planets constantly changes because new objects in the solar system are being discovered and classified. These objects need to meet certain criteria to be considered dwarf planets, so as our technology and understanding of the universe improve, the number of known dwarf planets can increase or decrease.
In what order are the planets listed from smallest to biggest in the solar system?
In order from least to greatest in mean radius:Vesta (protoplanet)Pallas (protoplanet)Charon+ (dwarf planet)Orcus (dwarf planet)Quaoar (dwarf planet)Ceres (dwarf planet)Sedna (dwarf planet)"Snow White" [2007 OR10]* (dwarf planet)Haumea* (dwarf planet)Makemake (dwarf planet)Pluto+ (dwarf planet)Eris (dwarf planet)Mercury (terrestrial planet)Mars (terrestrial planet)Venus (terrestrial planet)Earth (terrestrial planet)Neptune (ice giant)Uranus (ice giant)Saturn (gas giant)Jupiter (gas giant)*There is a slight discrepancy as to how Haumea ought to be measured, due to its unusual shape. This makes it slightly unclear as to which is considered larger between Haumea and "Snow White."+Binary planet
How big are the planets when they are put together?
if you add up the size of every planet including pluto (dwarf planet) makes a diameter of 17,980,42km.
How is a moon different from a planet or a dwarf planet?
What makes a moon a moon is the fact that it is smaller than the object it is orbiting, and is orbiting the object (the planet) constantly.The definition of a moon is "a natural satellite revolving around a planet". Since a satellite is an object that orbits a bigger object, usually a planet, and is not a planet due to its small size, it is considered a moon and not another planet.
What is the force that makes your weight change on different planets?
Gravity
What makes Pluto different from the planets?
It's smaller and colder
