Scientists believe that the moon is formed when a gigantic object the size of Mars collides with a new planet. Gravity gathers the debris from the crash to form the moon. "The moon and the earth are big in the sky one of the other when they make a statement today," said Arbita Roy, a postgraduate student in Pennsylvania, in a statement. . "The moon is moving away from the Earth at a rate of 4 cm a year.
The distance from the moon to the earth
The orbit of the moon around the earth is elliptical. At the nearest lunar slope, the moon approaches 363.104 kilometers (225.623 miles). At the end of the moon, 405 696 km of land. On average, the distance between the Earth and the Moon is about 388,400 km (238,855 miles). According to NASA, "This means that 30 planets the size of the Earth can slip between the Earth and the Moon.
The concept that the moon in a synchronous rotation with the earth
In other words, the moon turns around its axis at the same time it takes to turn around the Earth – 27 days and 8 hours, which is called the month of the stars. So we always see the same side of the moon: there is no "dark side of the moon". Instead, scientists refer to the moon as "the hidden face of the moon". NASA Satellite DSCOVR, which captured a video of the moon "photo-destroying" the Earth.
How long does it take to reach the moon
A series of factors determine the time needed to reach the moon. Human missions, for example, tend to take longer than satellites without passengers. If an object stops or does not stop on the moon.
The Soviet Union launched its first mission on the moon, Luna 1, in 1959. In the absence of propulsion system, the satellite was launched in the form of a ball in the air. space and the flight took 34 hours.
After the flight, the satellite entered the orbit of the Sun between the orbits of the Earth and Mars. It's still one of the fastest flights to the moon. In 2003, the European Space Agency (SMART) launched the first successful European satellite on the moon. Instead of walking on a direct path, SMART-1 climbed around the Earth to reach its satellite, reaching more than a year after its launch.
Instead of pushing, the SMART-1 used the ion engine for the first time, combined with gravity assisted maneuvers, to reach the moon, making it a fuel-efficient solution. The expanded path provided an overview of the Earth and Moon system.
NASA missions For the moon
NASA sent eight Apollo missions to the moon, six of which landed successfully. Apollo 8 was the first mission on another body and the infamous Apollo 13 disaster caused a trip around the moon rather than landing on its surface. They spent about three days traveling in space.
