The concept of dwarf planets is a recent one; earlier in astronomical history, planets were not differentiated. After guidelines were passed by the IAU, dwarf planets became a separate category, of which Pluto is a part. This is why Earth’s outermost planet got ousted from the list of main...
Major Dwarf Planets 主要矮行星 There are five recognised Dwarf planets in the solar system at the time of writing. This can increase in the future when one is discovered or the rules have changed. There are some candidates such as Ixion and Quaoar but they are awaiting confirmation. Ceres 谷...
The Kuiper Belt is populated by icy bodies that are remnants of the solar system's formation. These are the building blocks of planets. We now also know the surface of Pluto contains ices composed of methane, nitrogen, and other compounds familiar to us. It also seems to have a bright po...
“In the Milky Way, “ says Setiawan, “the more metals a star has , the more likely it is to have planets. “ Dwarf galaxies like the one in which HIP 13044 was born, however, have stars that are notably metal-poor. It was unclear until now whether that meant they’d also be ...
In 2006, the International Astronomical Union developed the first official criteria to differentiate asteroids, dwarf planets, and planets. To reach planetary status, an object must orbit the sun, have a spherical shape caused by its mass and gravity, and clear all other objects from its orbital...
Our star, 'The Sun' is one of many billions of other stars that make up The Milky Way Galaxy. Our Milky Way is one of many billions of galaxies that make up the physical part of the Universe. Galaxies also contain comets, asteroids, nebulas, planets etc Most galaxies are moving away...
