Our galaxy holds important celestial bodies that keep earth stable environment for all living creatures.The earth, moon, and sun are the bodies that are included in everyone's daily lives and they are important for everythings survival. The earth spins on an axis, one full spin is called a rotation.One full rotation takes 24 hours, 24 is one day, 12 hours of light and 12 hours of darkness. The earth orbits the sun, one full orbit is called a revolution, a revolution is one year, and a year is about 365¼ days. The earth's axis is tilted by 23.5°, that causes the temperature of the earth. IN the north pole there is more direct sunlight when it's tilted toward the sun and the south pole has less direct sunlight. When the south pole is tilted

The moon can be most easily viewed at night, but even sometimes during the day too. The moon rotates once on its axis each time it orbits earth. The moon appearance changes from earth, these changes are called lunar phases. There are 8 lunar phases, it starts with new moon that waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, third quarter, and waning crescent. Those are the 8 lunar phases and they all happen at least once in every month. An eclipse is an event when one object in space casts a shadow onto another, There are two types of eclipses. A lunar eclipse is when the moon moves through earth's shadow. A solar eclipse is when the moon is in between the sun and the earth, so the moon casts a shadow on some part of earth. The umbra of a shadow is the darkest part, the penumbra of a shadow if the lighter part around the umbra of a shadow. An eclipse doesn’t occur every month, thats because the moon is tilted 5° relative to the orbit of earth around the sun. The tilt is enough to place the moon out of earth's shadow so that a lunar eclipse is not able to …show more content…
Tides Are caused by different gravitational forces of the sun and the moon, but the moon is mainly responsible, which is called tidal force. How often tides occur and how tidal levels vary depend on the position of the moon as it orbits the earth. A high tide is when the sea water is above average sea level, and low tides are when the sea level is below average sea level. A tidal range is the difference between the levels of the ocean, the level of ocean is usually compared with the average water levels. Spring tides are the largest tidal range and happen when the sun, moon, and earth from a straight line. Neap tides are the smallest tidal range and occur when the sun, earth, and moon form a 90° angle. The rotation of the earth and moon's revolution around earth determine when tides
