It's the closest planet to the sun, so the "day" side gets HOT.
(it has a very slow rotation, about 2/3 of its year)
while the night side gets to radiate heat into outer space
(there's no atmosphere to help trap any of that heat).
Mercury
The heaviest planet in our solar system is Jupiter, while the lightest planet is Mercury. Jupiter is a gas giant with a mass greater than all the other planets combined, whereas Mercury is a small, rocky planet with a much lower mass.
There are two main similarities between Mercury and Pluto. One is their smaller sizes, although Pluto is far smaller than Mercury. The other is their extreme distance from the sun. So Mercury is the closest known planet to the sun while Pluto was considered the furthest.
No, Mercury does not have a twin planet. It is the smallest and innermost planet in our solar system, and there is no other planet that is exactly like Mercury in terms of its size, composition, and distance from the Sun.
Mercury is a planet that experiences extreme temperature variations between its day and night sides. During the day, temperatures can reach up to 800 degrees Fahrenheit (430 degrees Celsius), while at night, temperatures can drop to around -290 degrees Fahrenheit (-180 degrees Celsius).
Mercury is the planet that can experience extreme temperature variations between its day side and night side. The side facing the Sun can reach temperatures over 800°F (427°C), while the side facing away from the Sun can drop to below -290°F (-179°C) due to its lack of atmosphere to regulate temperatures.
mercury is very very heater than other planets
Temperatures on the side of a planet away from the sun can vary depending on the planet's distance from the sun, atmosphere, and other factors. In space, temperatures can drop significantly, sometimes reaching temperatures close to absolute zero (-273 degrees Celsius or -459 degrees Fahrenheit).
the planet which completes its journey first is mercury i think
Mercury.
Mercury is the closest planet to the sun.one side of mercury is hot(about 450 Celsius) the other side of the planet is cold(_180 celsius)
Mercury, with almost no atmosphere, is also closest to the sun and has the largest range of temperatures between the side facing the sun and the side facing away - a difference of about 600 K.
