Gravity and relative velocity are what keep anything in orbit about any object.
(Note: Apollo 8 returned to Earth on December 27, 1968.)
I don't know what search terms you are using, but there are lots and lots of photos of the Earth from space, both the complete planet and parts of it, taken by astronauts and automatic satellites. The most iconic is 'Earthrise' taken from Apollo 8. Try that as a search term. There are pictures of earth from space. They were taken by the Apollo rockets. One that was seen everywhere was shot from the 1969 moon landing. You may have seen it and assumed it wasn't real.
One is revolution and another is rotation that's is all I know for now sorry hope this helped a little. Comment. I think they are: 1) Rotation about its axis. 2) Orbiting around Earth. 3) Orbiting around the Sun.
The average length of the northern hemisphere summer, calculated as the average time from the June solstice until the September equinox, is about 93 days and 15½ hours. The average length of the southern hemisphere summer, calculated as the average time from the December solstice until the March equinox, is about 89 days. (The reason the southern hemisphere summers are shorter than the northern hemisphere summers is that orbiting objects travel faster the closer they are to what they're orbiting, and Earth is closest to the sun in early January and farthest from the sun in early July.)

Approximately 2.5 secs. A 'microwave' is an electro-magnetic radiation, in the same manner as light, and uv. radiation. Being an electro-magnetic radiation it will travel at the speed of light, which is 'c' = 3.8 x 10^8 m/s
Apollo 8
No, Apollo 8 was the first manned mission the orbit the moon but it did not land on it.
No, Apollo 8 was the first manned spacecraft to orbit the moon, but it did not land.
The Apollo 8 and Apollo 10 came close to the moon but did not land on it.
The Apollo 8 spacecraft orbited around the moon 10 times.
Apollo 8
The Apollo 8 was the first attempt to send a man and bring him after orbiting the moon. The astronauts,were Frank Borman , James Lovell and William Anders.. It was reported by the press . in India that as they flew on Christmas day Frank Borman took a bible and read from it.
There were six moon landings and two trips to the moon. Apollo 8 and 10.
Apollo 6 was an unmanned test flight, which was not intended to reach the moon. Apollo 8 was the first to orbit the moon. Apollo 11 was the first to land on the moon.
Apollo 8 was the first spacecraft to orbit the moon.
Apollo 8 did not blow up. Apollo 8 was the first manned spacecraft to orbit the moon. It returned to the Earth safely. Apollo 13 is the spacecraft that had an explosion while traveling to the moon.
Apollo 13, Apollo 1, Apollo 8, Apollo 10 and maybe some other ones. But missions Apollo 8 and Apollo 10 weren't planned to go to the moon. They were just preparing for Apollo 11.
