If this map was printed from a quality printer (300 pixels per inch) the earth would be invisible, and the width of the paper would need to be 475 feet. Credit: NASA. This graphic shows all eight moon phases we see as the Moon makes a complete orbit of Earth about every four weeks. The Moon (or Luna) is the Earth’s only natural satellite and was formed 4.6 billion years ago around some 30–50 million years after the formation of the solar system. We know that the Moon’s dark areas, called maria – which is Latin for seas – are not actually seas. Notice how few dark areas the far side has. We know that the moon was bombarded by meteorites and over time was filled with lava and violent volcanic activity as well. Today, we know that the Moon is covered by craters as well as dust and debris from comets, asteroids and meteoroid impacts. Most of the major planets – all except Mercury and Venus – have moons. There are currently 181 known moons in our solar system orbiting the various planets and dwarf planets. (Image: Castleski/Shutterstock) When we look at the moon, we can see the basics of it.

The impact sent chunks of Earth and the impactor into space that were pulled together by gravity, creating the Moon. We now observe the heliocentric model, where the Sun is the center of the solar system, and the universe expands outward. With a radius of about 1,080 miles (1,740 kilometers), the Moon is less than a third of the width of Earth. Beyond Saturn, Uranus has 27 known moons. I have been making simple observations of it for over thirty years, and they have allowed me to get pretty accurate values of the synodic and sidereal months. Even though we don’t really understand them, a lot can happen within these massive lengths of time and space. The discovery of atmospheres on Moons tells us a lot about how dynamic our solar system really is. That means we always see the same side of the Moon from our position on Earth. Info. As we finish exploring the wonders of Earth, we turn our attention to a large, cratered object orbiting only Click and drag to rotate the Moon. Moons – also known as natural satellites – orbit planets and asteroids in our solar system.
