3 times, because 3 goes into 18 and 51.
Mr. Glenn circled the globe three times during his first flight.
It completes 15.7 earth orbits per day.
It orbits the sun about 1.88 times. Therefore, a Martian year is about 10½ months longer than an Earth year.
The moon orbits the earth once every 28 days and therefore does just over 13 revolutions each year

John Glenn .
On February 20, 1962, NASA astronaut John Glenn flew the Friendship 7 mission becoming the third American in space and the first American to orbit the Earth circling the earth three times.

John Glenn. John Glenn, Jr. circled Earth in 1962 on the Mercury 6 space mission, becoming the first American to make a complete Earth orbit. He also served as U.S. Senator to Ohio (1975 - 1999)

Alan Shepherd was the first American to be launched atop a rocket. The mission was not intended to place him in orbit, only to bring him back safely on a sub-orbital trajectory. The mission was successful. John Glenn, now a US Senator from Ohio, was the first American to be launched, successfully injected into earth orbit, make several complete orbits, and return safely to earth.
Mercury orbits the Sun in about 88 Earth days. So, in 1060 days......You do the math.
That comes roughlyclose, if you happen to be the moon. Astronauts orbiting the earth make several orbits per day.
The axial tilt of the Earth's axis of rotation (spin) relative to the plane in which it orbits the Sun means that as it orbits the Sun it successive presents on or other pole towards the Sun. This causes the Earth's climatic seasons and the changes in day length experienced at high latitudes.because
Gravity provides the centripetal force to sustain orbits, F= mGM/r2
