Orbit and turning
Earth turns at an angle (an "axial tilt
") in relation to its path around the Sun.
Earth is part of the eight planets and many thousands of small bodies that move around the Sun as its solar system. The Solar System is moving through the Orion Arm of the Milky Way galaxy now, and will be for about the next 10,000 years.
Earth is about 150,000,000 kilometers or 93,000,000 miles away from the sun (this distance is called an "Astronomical Unit"). Earth moves on its orbit at an average speed of about 30 km or 19 mi a second. Earth turns all the way around about 365¼ times in the time it takes for Earth to go all the way around the sun. To make up this extra bit of a day every year, an additional day is used every four years. This is named a "leap year".
The Moon goes around Earth at an average distance of 400,000 kilometers (250,000 mi). It is locked to Earth, so that it always has the same half facing Earth; the other half is called the "dark side of the moon". It takes about 27⅓ days for the Moon to go all the way around Earth, but because Earth is moving around the Sun at the same time, it takes about 29½ days for the Moon to go from dark to bright to dark again. This is where the word "month" came from, even though most months now have 30 or 31 days.
