Abi, Mia, Aaliyah, Keeshan

The moon is the brightest object in our sky.The moon appears to be larger near the horizon than when it is higher in the sky.The appearance changes but the size doesn't change. The moon is always the same size. It is an optical illusion.

The moon was made about 4.5 billion years ago. All the parts of the moon that reflect light. The light comes from the sun. The moon is the Earth's only natural satellite. The distance from the Earth to the Moon is 384403 km. The first person to walk on the moon was Neil Armstrong in 1969. The moon has an orbit around the earth. It takes about 27.3 earth days for this to happen. The tides in the oceans are caused by the moon. It is the Moon's gravitational pull that causes it. A lunar eclipse occurs when the earth is between the sun and the moon.
