Hint: A planet is a cosmological body circling a star or stellar residue that is enormous enough to be curved by its own gravity, is not enormous enough to instigate thermonuclear synthesis, and – rendering to the International Astronomical Union but not all terrestrial researchers – has cleared its adjacent area of planetesimals.

Complete answer:
The planets were believed by Ptolemy to circle Earth in deferential and epicycle gesticulations. Though the impression that the planets circled the Sun had been recommended numerous times, it was not until the 17th century that this opinion was reinforced by proof from the initial telescopic astronomical explanations, achieved by Galileo Galilei. About the same time, by vigilant examination of pre-telescopic experimental information poised by Tycho Brahe, Johannes Kepler found the planets' trajectories were abstruse rather than circular. As experimental gears enhanced, astrophysicists saw that, like Earth, each of the planets revolved around an axis slanted with deference to its orbital pole, and some shared such structures as ice caps and seasons. Since the beginning of the Space Age, close reflection by space probes has found that Earth and the other planets share characters such as volcanism, hurricanes, tectonics, and even hydrology.
Thus, the answer is heat and light.

Note: Planets in the Solar System are separated into 2 key kinds: huge low-density massive planets, and tinier rock-strewn terrestrials. There are 8 planets in the Solar System conferring to the IAU description. In order of growing expanse from the Sun, they are the 4 terrestrials, Mercury, Venus, Earth, and Mars, then the 4 massive planets, Jupiter, Saturn, Uranus, and Neptune. 6 of the planets are circled by one or more natural satellites.
