The most popular theory regarding lunar formation is that a Mars-sized planetoid slammed into the Earth and flung molten debris into orbit around 40 million years after the solar system was created, according to scientists at the National Aeronautics and Space Administration (NASA). This is called t
There are varying theories on how the moon was created. Some scientists believe that it was created when a Mars-sized planet named Theia crashed into the Earth during the early years of the formation of the solar system.
When the moon is full, the moon is at its brightest, and the entire disk is visible. New moons occur when the Earth comes between the moon and the sun, resulting in a moon that is completely obscured by the Earth's shadow and is barely visible in the night sky.
The phases of the moon are determined by the angle at which sunlight approaches the moon relative to the position of the Earth. When the sun is behind the Earth, relative to the moon, full sunlight falls on the hemisphere of the moon that faces Earth. When the sun is behind the moon, relative to Ear
A red moon occurs when the Earth eclipses the moon from sunlight. The moon looks red due to dispersed light from Earth's sunrises and sunsets that is refracted back onto the moon's surface.
As of September 2014, there are three more blood moons expected to occur within the next two years. They are predicted to occur on Oct. 8, 2014, April 4, 2015, and Sept. 28, 2015.
The surface of the moon is generally a light gray color, although there are parts of the moon that are made up of dark gray rocks. The moon has a different appearance from the surface, from space and from the Earth.
The gravitational pull of the moon ensures that the earth remains in a constant position on its axis, despite the way it is moving around the axis. Without the moon, the earth would not be able to continuously rotate and it would be uninhabitable.
The moon has a diameter of 3474.8 kilometers. The moon is 27 percent the size of Earth but has only 1.2 percent of the Earth's mass.
American astronaut Buzz Aldrin was the second person to walk on the Earth's moon. Aldrin set foot on the moon on July 21, 1969, just a few minutes after Apollo 11 mission commander Neil Armstrong.
