No, a chemist is not likely to determine why planets orbit the Sun, because it is outside the scope of his field of study.
Besides this has already been determined from the observations of astronomers and theories developed by physicists using those observations. Currently Albert Einstein's theory of General Relativity gives the most accurate explanation of this (including irregularities in Mercury's orbit that could not be explained in any reasonable manner before General Relativity).
Planets orbit stars.
Orbital ephemera. They consider its position relative to the sun, earth/moon, and other planets. Over a period of days they can determine its orbit, and whether that orbit likely intersects ours.
Moons orbit around planets. They are natural satellites that are held in orbit by the planet's gravitational pull.
All planets orbit around a sun.
The 8 planets orbit around the Sun, in ellipses.
Planets orbit stars.
No. Planets orbit suns, while moons orbit planets. Planets do not orbit planets.
Orbital ephemera. They consider its position relative to the sun, earth/moon, and other planets. Over a period of days they can determine its orbit, and whether that orbit likely intersects ours.
The Sun has no moons. Moons orbit Planets > Planets orbit the Sun.
The planets do not orbit the Earth, they orbit the sun.
Moons orbit planets. Planets orbit stars. Some stars orbit other stars, or orbit their mutual center of gravity. Stars orbit the center of the galaxy. Galaxies may orbit the center of the "galactic group".
Yes all planets have a orbit
No. The planets orbit the sun.
The planets orbit the sun. The sun is at the center of our solar system and exerts a gravitational pull that keeps the planets in orbit around it.
Moons orbit around planets. They are natural satellites that are held in orbit by the planet's gravitational pull.
Like larger planets, dwarf planets also orbit the sun.
All planets orbit around a sun.
