The moon’s orbit around Earth is the shape of a oval. In the Northern Hemisphere, the winter solstice occurs during December. A rocket is pushed forward as a reaction to the expelling of hot gases through a nozzle at the rear.
The pull of gravity on the surface of the moon is on sixth that of Earth. Maria are regions once flooded by molten material. The darkest part of the moon’s shadow is the umbra. Humans first landed on the moon in 1969.
The two days on which the sun is overhead at either 23.5 degrees north or south are called solstices. Tides are the rise and fall of ocean water every 12.5 hours or so. Satellites with Geosynchronous orbits revolve around Earth in the same time it takes for Earth to rotate on its axis.
A lunar eclipse occurs only when the moon is in the Full phase. Each of the two days of the yer when neither hemisphere is tilted toward the sun is know as an equinox. In one year, Earth complete 365 rotations.
The day in March on which the sun is overhead at noon at the equator is called the vernal equinox. A lunar eclipse occurs during a full moon when Earth is directly between the moon and the sun. When the moon is in Earth’s umbra you see a total lunar eclipse. The first person to orbit Earth was Yuri Gagarin
