Which planets have the longest and shortest years?

Jupiter has the shortest revolution period and Venus has the longest.

How long is 1 year in space?

Why is that considered a year? Well, 365 days is about how long it takes for Earth to orbit all the way around the Sun one time. It’s not exactly this simple though. An Earth year is actually about 365 days, plus approximately 6 hours.

Has anyone been lost in space?

Soyuz 1 dooms cosmonaut: The first fatal accident in a space mission befell Soviet cosmonaut Vladimir Komarov, whose problem-plagued Soyuz 1 capsule crashed onto Russian soil in 1967. … The resulting drop in pressure also exposed the crew to the vacuum of space — the only human beings to ever experience such a fate.

Do astronauts age faster?

Telomeres and aging Our study proposed that the unique stresses and out-of-this-world exposures the astronauts experience during spaceflight – things like isolation, microgravity, high carbon dioxide levels and galactic cosmic rays – would accelerate telomere shortening and aging.

Which is the heaviest planet?

JupiterLargest Planet: Jupiter Jupiter is 2½ times more massive than the rest of the planets in the solar system combined.

Which planet has the slowest orbit around the sun?

Neptune8. Neptune travels around the sun at a speed of 5.43 km/s or 12,146 miles per hour. Although this is a very high rate of speed, Neptune still has the slowest orbital velocity of any of the planets.

What planet is the coldest?

UranusThe seventh planet from the sun, Uranus has the coldest atmosphere of any of the planets in the solar system, even though it is not the most distant.

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.

What planet is closest to the sun?

MercuryZipping around the sun in only 88 days, Mercury is the closest planet to the sun, and it’s also the smallest, only a little bit larger than Earth’s moon.

Do we age in space?

And for astronauts on the International Space Station, that means they get to age just a tiny bit slower than people on Earth. That’s because of time-dilation effects. First, time appears to move slower near massive objects because the object’s gravitational force bends space-time.

Which planet has shortest day?

planet JupiterThe planet Jupiter has the shortest day of all the eight major planets in the Solar System. It spins around on its axis once every 9 hr 55 min 29.69 sec. Jupiter has a small axial tilt of only 3.13 degrees, meaning it has little seasonal variation during its 11.86-year-long orbit of the Sun.

What planet takes 7 years to orbit the sun?

What planet is the most dense?

EarthEarth is the fourth smallest of the planets—though in terms of the rocky planets, it’s the largest—but it’s the most dense. Jupiter is the largest planet in the solar system, but it’s Saturn—the solar system’s second largest planet—that takes the prize for least dense.

How long is 1 hour in space?

That number times 1 hour is 0.0026 seconds. So a person at that deep space location would have a clock that would run for one hour, while that person calculated that our clock ran for 59 minutes, 59.9974 seconds.

How is 1 hour in space equal to 7 years on earth?

The time-dilation effect of Einstein’s relativity has nothing to do with space. It has to do with speed. The faster you’re moving, the slower time goes for you. So if you were on some planet moving extremely fast through space, like in the movie Interstellar, then yes, you could miss 7 years on Earth every hour.

What planet could we live on?

After the Earth, Mars is the most habitable planet in our solar system due to several reasons: Its soil contains water to extract. It isn’t too cold or too hot. There is enough sunlight to use solar panels.
