The Space and Earth is born! But how? When? To know the answers to these questions, I went to the Museum of Natural History with Mariestory.

    The Universe (or space) was born about 15 billion years ago, which was during the Big Bang. Also, the planet Earth was formed about 4.6 billion years ago. When the Earth was first born, all seven continents were connected with each other, which is called Pangaea.

    There are eight planets in our Solar System-Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. These names all come from the gods of Greece, interestingly.

   The planet turns on its axis. When it does, it is called a rotation, which takes one day. When a planet circles around the sun once, it is called a revolution.

    Thank you for reading my essay.  Bye~
