## How many Aus is Neptune from the Sun?

30 astronomical units

From an average distance of 2.8 billion miles (4.5 billion kilometers) Neptune is 30 astronomical units away from the Sun. One astronomical unit (abbreviated as AU) is the distance from the Sun to Earth. From this distance it takes sunlight 4 hours to travel from the Sun to Neptune.

## What would happen if you landed on Neptune?

As a gas giant (or ice giant) Neptune has no solid surface. … If a person were to attempt to stand on Neptune they would sink through the gaseous layers. As they descended they would experience increased temperatures and pressures until they finally touched down on the solid core itself.

## Can you see the sun from Neptune?

Although sunlight is about 100 times dimmer on Saturn than on Earth the sun would still be far too bright to look at without eye protection. … Neptune is about 2.8 billion miles from the sun. That’s about 30 times farther than the distance from Earth to the sun.

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

The \$720 million New Horizons mission launched in January 2006 speeding away from Earth at a record-breaking 36 400 mph (58 580 km/h). Even at that blistering pace it still took the probe 9.5 years to reach Pluto which was about 3 billion miles (5 billion km) from Earth on the day of the flyby.

## How cold is Neptune?

-373 degrees F.
The average temperature on Neptune is a brutally cold -373 degrees F. Triton Neptune’s largest satellite has the coldest temperature measured in our solar system at -391 degrees F. That is only 68 degrees Fahrenheit warmer than absolute zero a temperature in which all molecular action stops.

## How fast is a light year in mph?

670 616 629 mph
In a vacuum light travels at 670 616 629 mph (1 079 252 849 km/h). To find the distance of a light-year you multiply this speed by the number of hours in a year (8 766). The result: One light-year equals 5 878 625 370 000 miles (9.5 trillion km).May 31 2019

## Where is Neptune today?

constellation of Aquarius

Neptune is currently in the constellation of Aquarius.

## Why is Neptune blue?

The predominant blue color of the planet is a result of the absorption of red and infrared light by Neptune’s methane atmosphere. … The images are part of a series of images made by Hubble during nine orbits spanning one 16.11-hour rotation of Neptune.

## What was the first planet discovered?

The first new planet discovered was Uranus. It was discovered by the English astronomer Sir William Herschel in 1781. Herschel was one of the first modern astronomers.

## Do you age slower in space?

We all measure our experience in space-time differently. That’s because space-time isn’t flat — it’s curved and it can be warped by matter and energy. … 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.

## 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.

## Can the Earth fall out of orbit?

The escape velocity of the Earth is about 11 km/s. In other words anything on the Earth’s leading side would fly off into space continuing along the Earth’s orbital path around the sun. Anything on the trailing side would be pulverized against the Earth. It would be a horrible gooey mess.

## Can we live on Neptune?

Neptune’s lack of Oxygen

No other planet has this including Neptune which only has trace amounts of oxygen. It has a hydrogen helium and methane atmosphere. So it would be impossible for us to breath on the planet Neptune which is another obstacle for humans living there.
