The first spacecraft to orbit any other celestial object was the Soviet Luna probe, which took the first-ever photos of the far side of the Moon.
Usually the Moon (Earth's) is said to orbit Earth, although the latter is sometimes not regarded as a celestial body per se. There are also arguments based on the nature of the lunar orbit that it is actually co-orbiting the Sun along with the Earth, that Earth and our moon simply share an orbit.
Yes, the Apollo 8 mission of December 1968 was a success. It had the first manned spacecraft to leave earth orbit, the first manned spacecraft to reach the moon and to orbit another celestial body; enabled the first direct views of the far side of the moon, and generated one of spaceflights most famous photographs, that of earthrise during lunar orbit. It paved the way for remaining missions in the Apollo program including the later lunar landing of Apollo 11. The three crew, Borman, Lovell and Anders, completed mission objectives and returned safely to Earth.
No. Earth orbits the sun, not the other way around. Earth's orbit depends on the mass of the sun, not Earth's rotation. Earth's rotation does, however, give the appearance that celestial objects revolve around it.
Yuri Gagarin flew aboard Vostok 1 for 108 minutes or nearly a complete orbit of the Earth, a Soviet space mission and the first man in space.
It's because the Earth's axis is tilted. Therefore the plane of the equator is tilted (at about 23.5 degrees) away from the plane of the Earth's orbit. Therefore the celestial equator is tilted away from the ecliptic.
For example, the orbit (movement) of earth around the sun.
As seen from Earth, the yearly orbit traces the eclipticon the Earth's celestial sphere.
The Russian put the first man in earth orbit, he was Yuri Gagarin in the year 1961.

An object launched to orbit Earth or another celestial body.
It is the orbit. For example, the Earth is in orbit round the Sun.

Yes. 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.
The "ecliptic". In truth, the Sun doesn't move; the apparent motion of the Sun across the sky is caused by the Earth spinning, and the apparent motion of the Sun across the "celestial sphere" is caused by the Earth orbiting the Sun. But the plane of the Earth's orbit around the Sun is what causes the apparent motion of the Sun across the celestial sphere, so the "ecliptic" is actually the plane of the Earth's orbit.
Columbia completed the first shuttle mission to orbit and back successfully and landed on April 14, 1981
