Which planets have the longest and shortest years?
Which planet has the longest day and the shortest year.
The answer to both questions is Mercury.
It orbits the Sun every 88 days, and a Solar Day on Mercury lasts for two orbits which is 176 days..
Why is Uranus lying on its side?
The ice giant is surrounded by 13 faint rings and 27 small moons as it rotates at a nearly 90-degree angle from the plane of its orbit. This unique tilt makes Uranus appear to spin on its side, orbiting the Sun like a rolling ball.
Do you age slower on Mars?
1 Answer. Short answer: Most likely not, but we don’t really know. There are theories about how gravity affects the physiology of our body, and we know what aspects get affected by lack of gravity. The overwhelming majority of effects noted due to low gravity are negative.
What is the smoothest planet?
EuropaJupiter’s large icy moon Europa has the smoothest surface of any solid body in the Solar System. The only prominent relief on its surface are ridges a few hundred metres in height.
What is the hottest planet?
VenusVenus is the exception, as its proximity to the Sun and dense atmosphere make it our solar system’s hottest planet. The average temperatures of planets in our solar system are: Mercury – 800°F (430°C) during the day, -290°F (-180°C) at night. Venus – 880°F (471°C)
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.”
What 2 planets have 53 moons?
Let’s go in order from the Sun.Mercury and Venus. Up first are Mercury and Venus. … Earth (That’s us!) Up next is Earth, and of course we have one moon.Mars. Mars has two moons. … Jupiter. Next are the giant outer planets. … Saturn. Saturn has 53 moons that have been named. … Uranus and Neptune.
Which planet has no season?
MercuryAs the closest planet to the sun, Mercury’s climate varies significantly throughout its year, which equates to 88 Earth days. Mercury is also the only planet in our solar system without any tilt, so technically lacks seasons.

What planet is the most interesting?
The best planet is Uranus—Uranus the bizarre. Uranus the unique. Saturn may be flashy and pretty, and Jupiter may be huge and dramatic, but they can’t hold a candle to Uranus’s intrigue. While all the other planets spin like tops around the sun, Uranus lies on its side.
Are there 8 or 9 planets?
The order of the planets in the solar system, starting nearest the sun and working outward is the following: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and then the possible Planet Nine.
What would Planet 9 be called?
One of those questions regards the so-called Planet Nine. … The planet is named HD 106906 b, and it orbits a binary star 336 light-years away. It has a mass of about 11 Jupiters, and it orbits the stars at a distance of more than 730 times the distance from Earth to the Sun.
Can we live on Neptune?
Neptune, like the other gas giants in our solar system, doesn’t have much of a solid surface to live on. But the planet’s largest moon, Triton, could make an interesting place to set up a space colony. … Though there are slight winds in Triton’s thin atmosphere, you wouldn’t feel any breeze while standing on the surface.
Is the sun a planet?
The Sun is a star. There are lots of stars, but the Sun is the closest one to Earth. It is the center of our solar system.

Which planet has the longest day?
VenusSo, 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.
Is there a 9 planet?
Planet Nine is claimed to be five to 10 times as massive as Earth, in an orbit well beyond Neptune. A team led by Kevin Napier of the University of Michigan, Ann Arbor, decided to test whether selection bias was playing a role.
Which planet is closest to the sun?
MercuryMercury—the smallest planet in our solar system and closest to the Sun—is only slightly larger than Earth’s Moon. Mercury is the fastest planet, zipping around the Sun every 88 Earth days.
How long is 1 hour in space?
7 years1 hour in space is 7 years on earth.
Is a day really 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 my age on Mars?
A year on Mars is longer than a year on Earth—almost twice as long at 687 days. This is roughly 1.88 times the length of a year on Earth, so to calculate your age on Mars we simply have to divide your Earth age by 1.88.
