Our solar system consists of a bright yellow star, eight planets, nearly 150 moons, and thousands of smaller objects like asteroids and comets. If you wanted to see all eight planets from the Earth, all you need is a clear night and a pair of binoculars. That is basically how early astronomers observed the heavens before the invention of large land telescopes and then later space exploration itself. The development of orbital telescopes, such as the Hubble Space Telescope, and interstellar probes has enhanced our knowledge of the universe enormously.
