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.

## How many Earth years is a Lightyear?

A light-year is the distance light travels in one Earth year. One light-year is about 6 trillion miles (9 trillion km). That is a 6 with 12 zeros behind it!

## Can humans reach the sun?

In theory we could. But the trip is long — the sun is 93 million miles (about 150 million kilometers) away — and we don’t have the technology to safely get astronauts to the sun and back yet. … The sun’s surface is about 6 000 Kelvin which is 10 340 degrees Fahrenheit (5 726 degrees Celsius).

## 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).

## 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 old is the Earth?

4.543 billion years

## How close can the moon come to Earth?

If the Moon was in an orbit getting closer to Earth it could reach a distance of roughly 19 000 kilometres (11 800 miles) before the gravity of Earth began pulling its lunar companion apart – this distance is known as the ‘Roche limit’.

## How long would it take us to get 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.

## Can we travel at the speed of light?

So will it ever be possible for us to travel at light speed? Based on our current understanding of physics and the limits of the natural world the answer sadly is no. … So light-speed travel and faster-than-light travel are physical impossibilities especially for anything with mass such as spacecraft and humans.

## Has anyone died in space?

A total of 18 people have lost their lives either while in space or in preparation for a space mission in four separate incidents. Given the risks involved in space flight this number is surprisingly low. … The remaining four fatalities during spaceflight were all cosmonauts from the Soviet Union.

## Can we survive without sun?

All plants would die and eventually all animals that rely on plants for food — including humans — would die too. While some inventive humans might be able to survive on a Sun-less Earth for several days months or even years life without the Sun would eventually prove to be impossible to maintain on Earth.

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

The trip to Mars will take about seven months and about 300 million miles (480 million kilometers). During that journey engineers have several opportunities to adjust the spacecraft’s flight path to make sure its speed and direction are best for arrival at Jezero Crater on Mars.

## How big is the universe?

about 93 billion light-years

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 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 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.

## Why do stars twinkle?

As light from a star races through our atmosphere it bounces and bumps through the different layers bending the light before you see it. Since the hot and cold layers of air keep moving the bending of the light changes too which causes the star’s appearance to wobble or twinkle.

## How far can we see in space?

The farthest that Hubble has seen so far is about 10-15 billion light-years away. The farthest area looked at is called the Hubble Deep Field.

## How many years does the earth have left?

By that point all life on Earth will be extinct. The most probable fate of the planet is absorption by the Sun in about 7.5 billion years after the star has entered the red giant phase and expanded beyond the planet’s current orbit.

## When did life appear on Earth?

3.7 billion years
The earliest life forms we know of were microscopic organisms (microbes) that left signals of their presence in rocks about 3.7 billion years old.

## How long have humans existed?

While our ancestors have been around for about six million years the modern form of humans only evolved about 200 000 years ago. Civilization as we know it is only about 6 000 years old and industrialization started in the earnest only in the 1800s.

## Can we survive without the moon?

The moon influences life as we know it on Earth. It influences our oceans weather and the hours in our days. Without the moon tides would fall nights would be darker seasons would change and the length of our days would alter.

## Does the Earth fall?

Thanks to gravity the earth does fall. It is actually in a constant state of falling since it is in orbit around the sun. … Since gravity as a force is caused by mass it follows that the sun is the centre of our solar system it is the heaviest thing in it therefore all of the planets in our solar system orbit it.

## What happens if moon comes closer to Earth?

With the Moon coming closer and closer the Earth rotation would speed up our days would become shorter and shorter global temperatures would go down and no one would worry about climate change anymore. Unless asteroids burned the Earth to ashes then there would be no one to worry about anything.

## Does it rain diamonds on Jupiter?

New research by scientists apparently shows that it rains diamonds on Jupiter and Saturn. … According to the research lightning storms on the planets turn methane into soot which hardens into chunks of graphite and then diamonds as it falls.

## How long would it take to get to the moon?

It takes about 3 days for a spacecraft to reach the Moon. During that time a spacecraft travels at least 240 000 miles (386 400 kilometers) which is the distance between Earth and the Moon. The specific distance depends on the specific path chosen.

## How fast is warp speed?

In the sci-fi universe of “Star Trek ” spaceships with warp drives can zoom past the normally impenetrable limit of light speed or about 186 282 miles per second (299 792 kilometers per second) in a vacuum.

## How fast can a human go without dying?

This is a well documented field and the average maximum survivable g-force is about 16g (157m/s) sustained for 1 minute. However this limit depends on the individual whether the acceleration is applied to one’s entire body or just individual parts and the time in which the acceleration is endured over.

## How fast is the speed of dark?

Darkness travels at the speed of light. More accurately darkness does not exist by itself as a unique physical entity but is simply the absence of light.

## What would happen if the Earth stopped spinning?

At the Equator the earth’s rotational motion is at its fastest about a thousand miles an hour. If that motion suddenly stopped the momentum would send things flying eastward. Moving rocks and oceans would trigger earthquakes and tsunamis. The still-moving atmosphere would scour landscapes.

## What if the sun exploded?

The good news is that if the Sun were to explode – and it will eventually happen – it wouldn’t happen overnight. … During this process it will lose its outer layers to the cosmos leading to the creation of other stars and planets in the same way that the violent burst of the Big Bang created Earth.

## What happens if Earth falls 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. … Without the outward centripetal force to counteract the inward pull of gravity the Earth would begin falling towards the sun.
