Because the suns rays do not point to mercry
No.
well technically its not a planet no more but Pluto
Mercury is not the coldest planet because it has more solar radiation than all of the other planets. This is because it is closer to the Sun. However, Mercury is not the hottest planet in the Solar System. See related question.
Mercury is the inner planet that gets the coldest. This is because it has virtually no atmosphere to retain heat, resulting in extreme temperature variations between its day and night sides. Nighttime temperatures on Mercury can drop to around -290 degrees Fahrenheit (-180 degrees Celsius).
Mercury is an extreme planet. it is fastest of all the planets. also, it is one of the hottest and coldest planet too.
Saturn. It is the furthest from the Sun
Because it is has the hottest and coldest temperatures.
Mercury is the closest to the sun. Pluto is the very last planet in our solar system so that's what makes it the coldest planet.
Mercury is the hottest planet because it is the closest planet to the sun, and therefore receives more direct sunlight. Neptune is the coldest planet because it is the farthest planet from the sun, receiving very little sunlight and having a thick atmosphere that traps heat, resulting in cold temperatures.
The biggest planet in our solar system is Jupiter, the smallest planet is Mercury, the hottest planet is Venus due to its thick atmosphere trapping heat, and the coldest planet is Neptune, located farthest from the Sun.
