The word "planet" is spelled with six letters: p-l-a-n-e-t. The first two letters, "p" and "l," are pronounced with their standard phonetic sounds. The "a" in "planet" is pronounced with an /æ/ sound, like the "a" in "cat." The "e" is pronounced with a schwa /ə/ sound, which is similar to the "u" in "cup." The final two letters, "t" and "t," are pronounced with a simple /t/ sound. Together, these letters and sounds create the word "planet."
A planet is a celestial body that orbits around a star, has enough mass to maintain its shape due to gravity, and has cleared its orbit of other debris, such as asteroids or comets. Typically found within a solar system, planets are relatively large, spherical objects that do not emit their own light but instead reflect the light of their parent star. The term "planet" is derived from the Greek word "planētēs," meaning "wanderer," as these celestial bodies were observed to move across the night sky in ancient times.
Across the universe, planets come in a diverse range of sizes, compositions, and environments. They can be rocky like Earth or gas giants, and some are even believed to possess potential conditions for sustaining life. Examples of planets within our own solar system include Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune, while dwarf planets such as Pluto also exist.
The definition of a planet has undergone revision and controversy throughout history, with the International Astronomical Union (IAU) introducing a formal definition in 2006. According to this definition, a celestial body must meet three criteria to be classified as a planet: it must orbit around the Sun, be spherical in shape, and has cleared its orbit of other objects. This has resulted in the reclassification of some celestial bodies, such as Pluto, which is now considered a dwarf planet.
One of the celestial bodies moving round the sun like our earth-the planets whose orbits are within those of the earth are called inferior-viz., Mercury, Venus; those without that of the earth superior-viz., Mars, the Asteroids, Jupiter, Saturn, Uranus, and Neptune; the smaller planets are called asteroids.

The word "planet" can be traced back to the Greek word "planētēs", which means "wanderer". The ancient Greeks observed that unlike the other celestial bodies in the night sky, planets appeared to move across the sky in a wandering, erratic fashion. This concept was later adapted by the Romans, who used the Latin term "planeta" to refer to these wandering stars. Over time, the word "planet" became widely recognized in various languages to describe the celestial bodies that orbit around the Sun or other stars.
