The astronomer credited as the first to theorize that the planets orbit around the Sun (heliocentrism) is Nicolaus Copernicus. He developed the heliocentric model of the solar system, which proposed that the Sun was at the center and the planets, including Earth, revolved around it in circular orbits. This theory was a departure from the earlier geocentric model, which posited that Earth was at the center of the universe and everything orbited around it. Copernicus's work laid the foundation for the modern understanding of the solar system's structure and motion.
Copernicus was the first astronomer to forward the Helio (Sun) centric system of the the Solar System.
That is the Sun the centre of the system and all the planets orbit around the Sun.

The planets travel around the sun.
Though no one knows for certain who actually invented the zodiac calendar, historians and astronomers feel it was first in ancient Babylon. It was most likely around eighteen hundred years before Christ. It was based around the planets and stars.
the planets go around in circles around the sun
Aristarchus of Samos
It was Claudius Ptolemy, 98-160. His Ptolemaic system describing the planets' movements among the stars was generally accepted for about 1400 years. Until the computer age, the Ptolemaic model was also used in planetariums.

That the Earth and all the other planets rotate around the Sun... and not around the Earth........

Nicolaus Copernicus discovered why planets stay in orbit when he found that the planets revolve around the sun. He is credited with starting the Scientific Revolution through this discovery.
Yes, there are over 200 more planets outside the solar system, these planets are called extrasolar planets. There are also more then 170 solar systems inside of the Milky Way, on average astronomers find around 25 new planets a year.
an atmosphere, air or what the creature breathes and water
it was geilo i dont know his last name but if youu know him than well i dont know check your books kids.
That would be Saturn, but astronomers are finding very thin rings around other planets, too, like Neptune, for instance.

Early astronomers doubted that the planets, particularly the Earth, revolved around the sun because from the perspective of an observer on Earth, the planets seemed to be at rest. They believed that the sun particularly moved around the Earth.
