Group of stars:

Orbit
Constellation
Solar system
Comet

The correct answer is C. Constellation.

A constellation is a group of stars that appear to form a pattern in the night sky. Constellations are often named after mythological figures, animals, or objects. There are 88 official constellations recognized by the International Astronomical Union.

An orbit is the path that an object takes around another object in space. For example, the Earth orbits the Sun, and the Moon orbits the Earth.

A solar system is a star and all the objects that orbit it, including planets, moons, asteroids, and comets. The Solar System consists of the Sun, eight planets, and three dwarf planets. The planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. The dwarf planets are Pluto, Eris, Makemake, and Haumea.

A comet is a small body made of ice, dust, and rock that orbits the Sun. Comets are often visible in the night sky when they approach the Sun and their icy surfaces vaporize.
