Which planet has longest day?

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.

Which is the coldest planet?

The coldest planet in our solar system on record goes to Uranus which is closer to the Sun and 'only' about 20 times further away from the Sun than the Earth is. The lowest temperature recorded there was minus 224 degrees Celsius.

Why is a Mercury day so strange?

Mercury rotates slowly. One rotation takes nearly 59 Earth days to complete. However due to an orbital-rotational resonance ratio of 3:2, a fictitious observer on Mercury would see that a solar day from noon to noon would take about 176 Earth days to complete.

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.

What is the shortest night on Earth?

June 21 is the longest day and marks the shortest night in the northern hemisphere. The earth is slightly tilted as it orbits the Sun, and June is one of two times each year when that habit is most prominent: the solstice.

What planet has the 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).

What planet has no atmosphere?

Instead of an atmosphere, Mercury possesses a thin exosphere made up of atoms blasted off the surface by the solar wind and striking meteoroids. Mercury's exosphere is composed mostly of oxygen, sodium, hydrogen, helium, and potassium.

What planet rotates backwards slowly?

Venus is certainly considered very odd for spinning in the opposite direction to most other planets, but the strangeness of Venus doesn't end there. The planet rotates incredibly slowly, with the Venusian day equivalent to 243 Earth days, which is longer than the Venusian year of 225 Earth days.

Which two planets are nearly twins?

Venus is sometimes called Earth's twin because Venus and Earth are almost the same size, have about the same mass (they weigh about the same), and have a very similar composition (are made of the same material). They are also neighboring planets. However, Venus and Earth are also very different.

What 2 planets rotate differently?

If you look at the solar system from its north pole, then you will see all the planets orbiting the Sun counter clockwise and rotating on their axis counterclockwise, except for Venus and Uranus. Venus rotates clockwise while Uranus rolls on its side as it orbits the Sun.

Which planet is the windiest?

Saturn is also the 'windiest' planet, with atmospheric winds of up to 1600 kilometres per hour, much stronger than in the atmosphere of Jupiter. Saturn is composed mainly of hydrogen and helium.

Which planet is called the brightest planet?

Venus is so bright because its thick clouds reflect most of the sunlight that reaches it (about 70%) back into space, and because it is the closest planet to Earth. Venus can often be seen within a few hours after sunset or before sunrise as the brightest object in the sky (other than the moon). Q.

What should you not do during Mercury?

Hold off on signing any contracts

Since Mercury rules communication, a retrograde can cause contractual agreements to get muddled. "If you have no other choice, double-check all the fine print or get a second opinion before signing the dotted line," Bowles suggests.

Why does Mercury not rotate?

The leading theory for why Mercury did not end up rotating synchronously is that the moderate eccentricity (e=0.2) of Mercury's orbit caused the planet to become trapped in the 3/2 spin/orbit resonance as tidal torques from the Sun tugged on the planet.

When did Mars dry up?

Mars once ran red with rivers. The telltale tracks of past rivers, streams and lakes are visible today all over the planet. But about three billion years ago, they all dried up—and no one knows why.

Can you breathe air on Mars?

Mars does have an atmosphere, but it is about 100 times thinner than Earth's atmosphere and it has very little oxygen. The atmosphere on Mars is made up of mainly carbon dioxide. An astronaut on Mars would not be able to breathe the Martian air and would need a spacesuit with oxygen to work outdoors.
