Quick Answer: How Many Earth Days Is A Day On Mercury?

How many Earth days equal a Mercury day?

One Mercury solar day (one full day-night cycle) equals 176 Earth days – just over two years on Mercury.

How many Earth years does it take for Mercury?

However, it’s proximity to the Sun means that its average orbital velocity is a speedy 47.362 kilometers a second or 29.429 miles per second – approximately 170,500 km/h; 105,945 mph. At this rate, it takes Mercury 87.969 days, or the equivalent of 0.24 Earth years, to complete a single orbit of the Sun.

What planet has 48 hour days?

So, Venus has the longest day of any planet in our solar system. It completes one rotation every 243 Earth days. Its day lasts longer than its orbit.

How long is a night on Mercury in Earth days?

It takes Mercury about 88 Earth days to orbit the sun, while Earth takes 365 days. 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.

How long is an hour on Mercury?

On Mercury a day lasts 1,408 hours, and on Venus it lasts 5,832 hours. On Earth and Mars it’s very similar. Earth takes 24 hours to complete one spin, and Mars takes 25 hours. The gas giants rotate really fast.

Which planet has shortest day?

This means that Jupiter has the shortest day of all the planets in the Solar System. Since Jupiter is a gas planet, it does not rotate as a solid sphere. Jupiter’s equator rotates a bit faster than its polar regions at a speed of 28,273 miles/hour (about 43,000 kilometers/hour).

Which is the only planet that can sustain life?

Nonetheless, Earth is the only place in the Universe known to harbor life.

How old would I be on Pluto?

Age on Pluto: A year on Pluto is almost 248 Earth years long. This means that every living human is less than one Pluto year old.

What is the oldest planet?

At 12.7 billion years old, planet Psr B1620-26 B is almost three times the age of Earth, which formed some 4.5 billion years ago. This exoplanet, the oldest ever detected in our Milky Way galaxy, has been nicknamed “Methuselah” or the “Genesis planet” on account of its extreme old age.

Why is a day 23 hours and 56 minutes?

Not quite 24 hours, it turns out — it’s precisely 23 hours and 56 minutes. But because Earth is constantly moving along its orbit around the sun, a different point on the planet faces the sun directly at the end of that 360-degree spin. “If we didn’t orbit the sun, both days would be the same.”

How is 1 hour 7 years in space?

The first planet they land on is close to a supermassive black hole, dubbed Gargantuan, whose gravitational pull causes massive waves on the planet that toss their spacecraft about. Its proximity to the black hole also causes an extreme time dilation, where one hour on the distant planet equals 7 years on Earth.

Which planet rotates the fastest?

Jupiter is the fastest spinning planet in our Solar System rotating on average once in just under 10 hours. That is very fast especially considering how large Jupiter is. This means that Jupiter has the shortest days of all the planets in the Solar System.

What is the hottest planet?

Venus is the hottest planet in the solar system. Although Venus is not the planet closest to the sun, its dense atmosphere traps heat in a runaway version of the greenhouse effect that warms Earth.

How cold is it on the dark side of Mercury?

On its dark side, Mercury gets very cold because it has almost no atmosphere to hold in heat and keep the surface warm. The temperature can drop down to minus 300 degrees Fahrenheit. Sunlight never reaches into the bottoms of some craters near Mercury’s poles.
