What is a day like on Mercury?
A planet’s day is the time it takes the planet to rotate or spin once on its axis. Mercury rotates very slowly compared to Earth so a day on Mercury is much longer than a day on Earth. A day on Mercury is 58.646 Earth days or 1407.5 hours long while a day on Earth is 23.934 hours long.
Does Mercury have a night?
It takes about 176 Earth days for Mercury to rotate on its axis (from sunrise to sunrise), while Earth takes only 24 hours. On Mercury, it is daytime for one year, and night for one year.
Does Mercury have hot days and cold nights?
The day side of the planet reaches temperatures of up to 800 degrees Fahrenheit (427 degrees Celsius). In contrast, the chilly night side can get as cold as minus 290 F (minus 180 C). The planet has an average temperature of 332 F (167 C). These variations are relatively long-lived.
How much is a day on Mercury?
Option 2: A Table
| Planet | Day Length |
|---|---|
| Mercury | 1,408 hours |
| Venus | 5,832 hours |
| Earth | 24 hours |
| Mars | 25 hours |
Is time slower on Mercury?
The time dilation on Mercury is mostly negligible. At closest pass to the sun, 47 million KM, the gravitation field strength from the sun is less than 2% the gravitation from Mercury, so that’s virtually nothing.
How long is a night on Mercury?
Then it resumes its normal westward motion, and as Mercury moves farther from the Sun, the solar disk begins to shrink in size until sunset, 88 Earth days after sunrise. What a day! And then, for a period lasting 88 Earth days, it is night for you.
Does Mercury have any moons?
Of the terrestrial (rocky) planets of the inner solar system, neither Mercury nor Venus have any moons at all, Earth has one and Mars has its two small moons….Read More.

What is the diurnal cycle on Mercury?
Equally unusual is the diurnal cycle on Mercury – i.e. the cycle of day and night. A single year lasts only 88 days on Mercury, but thanks again to its slow rotation, a day lasts twice as long! That means that if you could stand on the surface of Mercury, it would take a staggering 176 Earth days for the Sun to rise,…
How many days are there in a year on Mercury?
Time on Mercury A day on Mercury lasts 59 Earth days. A year on Mercury lasts 88 Earth days.
Why does Mercury have extreme night and day variations?
In any case, Mercury’s lack of a viable atmosphere is the reason why it is unable to retain heat from the Sun, which leads to extreme variations between night and day for the rocky planet.
How long does it take for Mercury to orbit the Sun?
One day on Mercury (the time it takes for Mercury to rotate or spin once with respect to the stars) takes 59 Earth days. One day-night cycle on Mercury takes 175.97 Earth days. Mercury makes a complete orbit around the Sun (a year in Mercury time) in just 88 Earth days.
