Who was the first astrounaut to land on the moon?

Neil Armstrong was the first astronaut to land on the moon on July 20, 1969, as part of the Apollo 11 mission. He famously stated, "That's one small step for man, one giant leap for mankind," as he became the first human to walk on the lunar surface.


An astrounaut lands on a planet that has the same mass as earth and twice the diameterhow does the astrounaut's weight differ from that on earth?

The force between two objects due to gravity is proportional to the product of the two masses. That part doesn't change compared to his weight on earth.The force is also inversely proportional to the square of the distance between their centers. On the planet with a diameter equal to twice the earth's diameter, the distance is changed by a factor of 2, so the force is changed by a factor of (1/22) = 1/4. His weight on the alien planet is 25% of his weight on earth. Naturally we're assuming that the planet's mass is symmetrically distributed. It doesn't have to be homogeneous with constant density throughout, but it has to be evenly spread around the center. The geometric center of the sphere also has to be its center of mass, with no big off-center lumps.


What is are solare flare?

A solar flare is a magnetically charged, hundreds-of-lightyears-long loop of plasma that shoots out of the sun as a result of a magnetic disturbance. the particles it gives off can cause damage to electrical devices, cause blackouts, and seriously injure any astrounaut unlucky enough to be exposed to it.
