For each of the following parts, find the most possible type of object by considering the descriptions, and explain your answer. Each part is independent. The possible types are red giant, galaxy, planetary system, planet, dwarf planet, red dwarf, white dwarf, brown dwarf, satellite, asteroid, comet, protostar, star, star cluster, galaxy cluster, supercluster, emission nebula, reflection nebula dark nebula (a) This object moves around the Sun. The nearest distance to the Sun is 0.5 AU, and the farthest distance from the Sun is 1000 AU. (b) This object is red in colour. The density is much lower than that of a star. (c) The mass of this object is the same as that of the Sun. It does not fuse hydrogen. (d) This object moves in a circular orbit about the Sun. Its orbit is between those of Mars and Jupiter. It is round in shape. (e) This object burns hydrogen in a region surrounding its helium core.
