I'm not aware that any observer EVER argued that "all planets except Earth" orbited the Sun. The first person we know of to argue that the Sun was the center of things, and that the Earth orbited the Sun, was Aristarchus of Samos, a Greek astronomer and mathematician about 2400 years ago.
John Glenn orbited the earth, the first American to do so. He was forty at the time.
The name of John Glenn's space shuttle when he first orbited the Earth in 1962 was Friendship 7.
None. It was launched into low-Earth orbit and stayed there until it fell back in the atmosphere and burned up.
On 12 April 1961, Gagarin became the first man to travel into space
No, Brahe did not believe in the heliocentric model; he proposed a geocentric model where planets orbited the Sun and the Sun orbited the Earth. It was Johannes Kepler who later discovered that planets orbit the Sun in an elliptical path, using Brahe's detailed observational data.

It was Johannes Kepler.

No animal has orbited the moon other than man. Dogs and monkeys have orbited the earth.
ANSWER Sir Isak Newton was the first person to realise that the force of gravity was universal. It is Kepler motion that describes the elliptically orbits of the planets.
Niels Bohr
Johannes Kepler was the first to state that planets move in elliptical orbits.
John Glenn orbited the earth, the first American to do so. He was forty at the time.
He first suggested that the Earth (and the other planets that were then known) rotated around the Sun instead of the other way around.

None. It was launched into low-Earth orbit and stayed there until it fell back in the atmosphere and burned up.
