It completes one rotation in 243 Earth days — the longest day of any planet in our solar system, even longer than a whole year on Venus. … On Venus, one day-night cycle takes 117 Earth days because Venus rotates in the direction opposite of its orbital revolution around the Sun.

Why does Venus have the longest rotation period of all the planets?
The sun’s gravitational pull is very strong on Venus and Mercury, making their rotations very slow and their days longer than their years.
Does Venus have the longest rotation period?
Venus has the longest rotation period (day) of all the major planets in the Solar System. While the Earth takes 23 hrs 56 mins 04 secs to complete one rotation, Venus takes 243.16 ‘Earth days’ to spin once through 360 degrees.
What planet has the longest day in the universe?
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. It orbits the Sun every 224.65 Earth days, so a day is nearly 20 Earth days longer than its year.
How long is 1 hour in space?
1 hour in space is 7 years on earth.
Is Venus hot or cold?
The average temperature on Venus is 864 degrees Fahrenheit (462 degrees Celsius). Temperature changes slightly traveling through the atmosphere, growing cooler farther away from the surface. Lead would melt on the surface of the planet, where the temperature is around 872 F (467 C).
Why is Venus called Earth’s sister?
Venus is a terrestrial planet and is sometimes called Earth’s “sister planet” because of their similar size, mass, proximity to the Sun, and bulk composition. It is radically different from Earth in other respects.
Why is Venus so close?
Because Venus is closer to the Sun, its orbit is smaller and it moves around the Sun faster than Earth does (one orbit for Venus takes 225 Earth days, as opposed to our 365 days). So soon enough it reaches a position in its orbit relative to Earth where it appears to the side of the Sun from our point of view.
Is there life on Venus?
Although there is little possibility of existing life near the surface of Venus, the altitudes about 50 km (31 mi) above the surface have a mild temperature, and hence there are still some opinions in favor of such a possibility in the atmosphere of Venus.
Is a day exactly 24 hours?
On Earth, a solar day is around 24 hours. However, Earth’s orbit is elliptical, meaning it’s not a perfect circle. That means some solar days on Earth are a few minutes longer than 24 hours and some are a few minutes shorter. … On Earth, a sidereal day is almost exactly 23 hours and 56 minutes.
What is the first 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 many hours is a day on Venus?

Is there a 9 planet?
