What is the unique planet of solar system and why?

Answer 1

Mercury is the closest to the sun and is very hot.

Venus is the hottest planet in the Solar system; it has mini volcano's all over it with storms and lightning.

Earth has people like us and has so many lifeforms to do with plants and animals.

Mars is the planet that it thought to have aliens and other lifeforms there and has been landed on by allot of rockets.

Jupiter is the planet that is very soft. It is not firm but jello like; it has not been fit to land on by NASA because of these reasons, it is the largest planet.

Saturn has rings around it of cold air and is different colours every 1,000,000 (and over) years.

Neptune is a gas planet and is covered in helium.

Uranus has bands of clouds, storm clouds all around it.

Uranus spins differently from most planets. It seems to be tilted "sideways" instead of right-side up. At the time of Voyager 2's passage, Uranus' south pole was pointed almost directly at the Sun.

Pluto is the smallest planet in the solar system.

All planets are unique.

Answer 2

Mercury is considered the unique planet of the solar system due to its extreme temperature variations, having the greatest temperature differences between day and night. During the day, temperatures can reach up to 800 degrees Fahrenheit (427 degrees Celsius), while at night they can drop to -290 degrees Fahrenheit (-179 degrees Celsius) due to its lack of atmosphere to retain heat.
