      I don’t investigate that, but over the years astronomers and other scientists have found out how our Solar system was born.

      It started with a huge cloud of gas and small rock particles in space. Gravity made the cloud get smaller and denser as it collapsed in on itself.

      The centre of the cloud became very hot and formed our star, the Sun.

      Some of the cloud didn’t fall into the centre but stayed outside orbiting around. That stuff became the planets, moons, asteroids and comets we see today.
