2.A star bigger than the Sun?
3. A constellation?
4. A very light planet made up mostly of gases?

Answer 1

Answer:

(1)Of the inner planets, Mercury and Venus have no natural satellites; Earth has one large natural satellite, known as the Moon; and Mars has two tiny natural satellites, Phobos and Deimos.

(2)The largest known star in the universe is UY Scuti, a hypergiant with a radius around 1,700 times larger than the sun

(3)A constellation is a group of stars that appears to form a pattern or picture like Orion the Great Hunter, Leo the Lion, or Taurus the Bull. Constellations are easily recognizable patterns that help people orient themselves using the night sky. There are 88 “official” constellations

(4)Uranus is the second least dense planet in the solar system, indicating that it is made up mostly of ices. Unlike Jupiter and Saturn, which are composed predominantly of hydrogen and helium, Uranus contains only a small portion of these light elements

(5)An asterism is a group of recognizable stars, like your definition says. However, it's usually a group within a constellation. A good example of an asterism is the Big Dipper (or the Plough, if you're in the UK). It's a familiar group of stars, but by itself it's not a constellation
