In which planet day is longest?

In which planet day is longest?

It was already known that Venus has the longest day – the time the planet takes for a single rotation on its axis – of any planet in our solar system, though there were discrepancies among previous estimates.

Is a day longer than a year on Mercury?

One Mercury solar day (one full day-night cycle) equals 176 Earth days – just over two years on Mercury. Mercury’s axis of rotation is tilted just 2 degrees with respect to the plane of its orbit around the Sun.

Which planet has shortest year and longest day?

Mercury has the shortest year (88 Earth days), and Neptune has the longest year (165 Earth years). Planets closer to the Sun have shorter year, because their orbits are smaller. Mercury, the innermost planet in the solar system, completes an orbit in 88 days.

Which planet has longest year?

Given its distance from the Sun, Neptune has the longest orbital period of any planet in the Solar System. As such, a year on Neptune is the longest of any planet, lasting the equivalent of 164.8 years (or 60,182 Earth days).

Which planet has the slowest day?

The Planet Venus has the slowest rotation rate because one day there is longer than the year on Venus or longer than its revolution around the sun. The Neptunian day is shorter than our planet earth.

Which planet is the coldest?

Uranus holds the record for the coldest temperature ever measured in the Solar System: a very chilly -224℃. The temperature on Neptune is still very cold, of course – usually around -214℃ – but Uranus beats that. The reason why Uranus is so cold is nothing to do with its distance from the Sun.

What is the hottest planet?

Venus’ thick atmosphere traps heat creating a runaway greenhouse effect – making it the hottest planet in our solar system with surface temperatures hot enough to melt lead. The greenhouse effect makes Venus roughly 700°F (390°C) hotter than it would be without a greenhouse effect.

Is Mercury hot or cold?

It is understood that the sunny side may reach temperatures of 750 to 800 degrees F., while the nighttime temperature plummets to nearly -330 degrees F. The average temperature on Mercury is a balmy 354 degrees F.

What color is Venus?

Viewed through a telescope, Venus presents a brilliant yellow-white, essentially featureless face to the observer. Its obscured appearance results from the surface of the planet being hidden from sight by a continuous and permanent cover of clouds. Features in the clouds are difficult to see in visible light.

Which is called the blue planet?

Over 71 percent of the Earth is covered with water. Therefore from outer space it appears blue and so Earth is called the ‘Blue Planet’.

Which planet has the longest month?

This is also referred to as its rotational period. So, Venus has the longest day of any planet in our solar system. It completes one rotation every 243 Earth days.

Why is Venus longest day?

1. A day on Venus is longer than a year. It takes Venus longer to rotate once on its axis than to complete one orbit of the Sun. That’s 243 Earth days to rotate once – the longest rotation of any planet in the Solar System – and only 224.7 Earth days to complete an orbit of the Sun.

Which planet has shortest year?

Since Mercury is the fastest planet and has the shortest distance to travel around the Sun, it has the shortest year of all the planets in our solar system – 88 days.

What is the nickname of Saturn?

Although the other gas giants in the solar system — Jupiter, Uranus and Neptune — also have rings, Saturn’s rings are particularly prominent, earning it the nickname the “Ringed Planet.”

What is the 2nd heaviest planet?

Hence second biggest planet in the solar system is Saturn. Was this answer helpful?

Which planet rotates 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.

Which is the fastest day?

Earth completed its normal 24-hour rotation 1.59 milliseconds fast on June 29, breaking the record for the shortest day in modern history. Sign up for CNN’s Wonder Theory science newsletter. Explore the universe with news on fascinating discoveries, scientific advancements and more.

Which planet has the fastest days?

Jupiter is the fastest spinning planet in our Solar System. Its period of rotation is just 10 hours. This means that Jupiter has the shortest day amongst all the planets in our Solar System.

On which planet is the day of 287 longest duration?

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.

Which planet is the hottest?

Venus’ thick atmosphere traps heat creating a runaway greenhouse effect – making it the hottest planet in our solar system with surface temperatures hot enough to melt lead. The greenhouse effect makes Venus roughly 700°F (390°C) hotter than it would be without a greenhouse effect.

Which planet has the shortest year?

Since Mercury is the fastest planet and has the shortest distance to travel around the Sun, it has the shortest year of all the planets in our solar system – 88 days.

How long is Venus’s day?

Time on Venus A day on Venus lasts 243 Earth days. A year on Venus lasts 225 Earth days.
