Venus has the highest albedo it is the percentage of light reflect back from a light source. how strongly it reflects light from light sources such as the Sun. It is therefore a more specific form of the term reflectivity. Albedo is defined as the ratio of total-reflected to incident electromagnetic radiation.
Divided in to 2 major categories plutoides and asteroids, a celestial body orbiting the Sun that is massive enough to be rounded by its own gravity but has not cleared its neighbouring region of planetesimals and is not a satellite. More explicitly, it has to have sufficient mass to overcome its compressive strength and achieve hydrostatic equilibrium.
plutoides are ice they are located all the way out in space in the kiuper belt. Plutoids are celestial bodies in orbit around the Sun at a semimajor axis greater than that of Neptune that have sufficient mass for their self-gravity to overcome rigid body forces so that they assume a hydrostatic equilibrium (near-spherical) shape, and that have not cleared the neighbourhood around their orbit. Satellites of plutoids are not plutoids themselves
discovered a year before Eris is the first of the kipper belt dwarf plantes
Trans Neptunian Objects
TNO is a name astronomers give to anything that orbits or goes around the Sun beyond the planet Neptune but it is not big enough to be a planet or a moon
Eris (UB 313)
the second plutoid to be found it is also the largest
plutos biggest moon
soild rocks it needs to have a specific orbit around the sun, sometimes called minor planets or planetoids, are small Solar System bodies in orbit around the Sun, especially in the inner Solar System; they are smaller than planets but larger than meteoroids.
located between mars and Jupiter not every asteroid is located in this belt, the region of the Solar System located roughly between the orbits of the planets Mars and Jupiter. It is occupied by numerous irregularly shaped bodies called asteroids or minor planets. The asteroid belt region is also termed the main belt to distinguish it from other concentrations of minor planets within the Solar System, such as the Kuiper belt and scattered disc.
