## How many years away is Mars?

On average the distance between Earth and Mars is 140 million miles according to Nasa. If you were to reach Mars based on the current speeds of spaceships it would take roughly nine months according to the Nasa Goddard Space Flight Centre’s website.

## How many years is a light years?

One light year is equal to the distance that light travels in one year (it is about ten trillion kilometers or six trillion miles). One light years is equal to approx 6.5×10^5 earht s years.

## What distance is 1 light year closest to?

A light-year is the distance light travels in one year. How far is that? Multiply the number of seconds in one year by the number of miles or kilometers that light travels in one second and there you have it: one light-year. It’s about 5.9 trillion miles (9.5 trillion km).

## How long would it take to get to Moon?

## Can you stand on Pluto?

Pluto is only about two-thirds as wide as Earth’s moon and has about the same surface area as Russia. … As a comparison on Earth you could blot out the full moon with your thumb if you held out your arm but it would take almost your entire fist to block Charon while standing on Pluto Stern said.

## Would we age faster on Mars?

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 nearest habitable planet?

NASA considers exoplanet Kepler-452b and its star to be the closest analog to our planet and Sun so far. Though it’s 60% larger than Earth in diameter Kepler-452b is thought to be rocky and within the habitable zone of a G-type star similar to ours.

## Where is Voyager 1 now?

Voyager 1 is currently in the constellation of Ophiucus. The current Right Ascension of Voyager 1 is 17h 13m 23s and the Declination is +12° 02′ 11” (topocentric coordinates computed for the selected location: Greenwich United Kingdom [change]).

## How many years would it take to get to the sun?

It would be faster to fly to the sun: It would take 169 090 hours to fly there at 550 miles per hour. It would take 7 045 days to fly there at 550 miles per hour. It would take 19.3 years to fly there.

## How long would it take to get from Earth to Jupiter?

The distance between Earth and Jupiter depends on the orbits of each planet but can reach more than 600 million miles. Depending on what the missions do and where they go it can take around two years to six years to reach Jupiter.

## How long does it take to get back to Earth from space?

The ride home from the International Space Station sees the astronauts brake from 28 800 km/h to a standstill at touchdown in barely three hours.

## Is going to Mars a one way trip?

Mars One initially estimated a one-way trip excluding the cost of maintaining four astronauts on Mars until they die at US\$6 billion.

## Is the sun 1 Lightyear away from Earth?

It takes 8.3 minutes for light to travel from the Sun to the Earth (a distance of 1.58 × 10-5 light-years). The most distant space probe Voyager 1 was 13 light hours (only 1.5 × 10-3 light years) away from Earth in September 2004. It took Voyager 27 years to cover that distance.

## What is the closest star to Earth?

The closest star to Earth is a triple-star system called Alpha Centauri. The two main stars are Alpha Centauri A and Alpha Centauri B which form a binary pair. They are about 4.35 light-years from Earth according to NASA.

## How many galaxies are there?

The Hubble Deep Field an extremely long exposure of a relatively empty part of the sky provided evidence that there are about 125 billion (1.25×1011) galaxies in the observable universe.

## How big is the universe?

The proper distance—the distance as would be measured at a specific time including the present—between Earth and the edge of the observable universe is 46 billion light-years (14 billion parsecs) making the diameter of the observable universe about 93 billion light-years (28 billion parsecs).

## How long would it take to travel 4 light years?

Last year astronomers raised the possibility that our nearest neighbor Proxima Centauri has several potentially habitable exoplanets that could fit the bill. Proxima Centauri is 4.2 light-years from Earth a distance that would take about 6 300 years to travel using current technology.

## How many Earths can fit in the sun?

1.3 million Earths
If you divide the volume of the sun by the volume of the Earth you get that roughly 1.3 million Earths can fit inside the sun.

## How long is 1 hour in space?

Answer: 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 long did it take Apollo 11 to get back to Earth?

eight days

They returned to Earth and splashed down in the Pacific Ocean on July 24 after more than eight days in space.

## How long does it take to space?

It can take anywhere from 6 hours to 3 days to get to the International Space Station depending on the spacecraft and mission profile. It took the Apollo astronauts about three days to get to the Moon.

## Can we live in Earth?

A special planet: the habitable Earth

What makes the Earth habitable? It is the right distance from the Sun it is protected from harmful solar radiation by its magnetic field it is kept warm by an insulating atmosphere and it has the right chemical ingredients for life including water and carbon.

## How cold is space?

Far outside our solar system and out past the distant reachers of our galaxy—in the vast nothingness of space—the distance between gas and dust particles grows limiting their ability to transfer heat. Temperatures in these vacuous regions can plummet to about -455 degrees Fahrenheit (2.7 kelvin).Sep 25 2020

## Can you land on Saturn’s rings?

Surface. As a gas giant Saturn doesn’t have a true surface. The planet is mostly swirling gases and liquids deeper down. While a spacecraft would have nowhere to land on Saturn it wouldn’t be able to fly through unscathed either.

## Is an hour in space 7 years on earth?

The first planet they land on is close to a supermassive black hole dubbed Gargantuan whose gravitational pull causes massive waves on the planet that toss their spacecraft about. Its proximity to the black hole also causes an extreme time dilation where one hour on the distant planet equals 7 years on Earth.

## Does hair grow in space?

Researchers found a number of genes that inhibit hair growth were more active during spaceflight suggesting it may grow more slowly or stop altogether while in orbit. But the study also suggests the hair follicles of men and women may react differently to the environment in space.

## How long can humans stay in space?

Astronauts need space suits to stay alive. You could only last 15 seconds without a spacesuit — you’d die of asphyxiation or you’ll freeze. If there’s any air left in your lungs they will rupture.

## Can you breathe on Mars?

The atmosphere on Mars is mostly made of carbon dioxide. It is also 100 times thinner than Earth’s atmosphere so even if it did have a similar composition to the air here humans would be unable to breathe it to survive.

## Can you see Mercury from Earth?

Why it matters — Mercury is the closest planet to the Sun so it is difficult to spot with the naked eye. The light of the star obscures it from our view from Earth.
