## How far is Earth from the Sun Kids?

The distance between the Earth and the Sun is about one hundred and fifty million kilometres. This is a big number and so astronomers use the astronomical unit to describe this distance.

## How old is the earth?

4.543 billion years

## What if Earth was closer to the sun?

The closer you are to the sun the hotter the climate. Even a small move closer to the sun could have a huge impact. That’s because warming would cause glaciers to melt raising sea levels and flooding most of the planet. Without land to absorb some of the sun’s heat temperatures on Earth would continue to rise.

## How far can you 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 light seconds away is the sun?

499.0 light-seconds

The average distance between Earth and the Sun (the astronomical unit) is 499.0 light-seconds.

## How far is space from Earth?

Experts have suggested the actual boundary between Earth and space lies anywhere from a mere 18.5 miles (30km) above the surface to more than a million miles (1.6 million km) away.

## How long will the earth last?

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.

## Who discovered Earth?

Eratosthenes

By around 500 B.C. most ancient Greeks believed that Earth was round not flat. But they had no idea how big the planet is until about 240 B.C. when Eratosthenes devised a clever method of estimating its circumference.

## 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 breathe without gravity?

As long as the air around us is thick enough we can breathe regardless of gravity. On Earth gravity is what holds our atmosphere. When astronauts go into space they can breath because their space ships and space suits keep the air around them even though gravity is very weak.

## 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.

## Does space ever end?

No they don’t believe there’s an end to space. However we can only see a certain volume of all that’s out there. Since the universe is 13.8 billion years old light from a galaxy more than 13.8 billion light-years away hasn’t had time to reach us yet so we have no way of knowing such a galaxy exists.

## What is in the end of universe?

Astronomers once thought the universe could collapse in a Big Crunch. Now most agree it will end with a Big Freeze. … Trillions of years in the future long after Earth is destroyed the universe will drift apart until galaxy and star formation ceases.

## 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 many Earths can you 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.

## 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 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 airplanes fly in space?

There’s simply no air to travel over and under an airplane’s wings in space which is a main reason airplanes can’t fly in space. Another reason airplanes can’t fly in space is because they require air to generate combustion. … Since there isn’t any air in space airplanes must stay within the Earth’s atmosphere.

## Can we go to another galaxy?

The technology required to travel between galaxies is far beyond humanity’s present capabilities and currently only the subject of speculation hypothesis and science fiction. However theoretically speaking there is nothing to conclusively indicate that intergalactic travel is impossible.

## How long until Earth runs out of oxygen?

approximately 1 billion years

The extrapolated data from these simulations determined that Earth will lose its oxygen-rich atmosphere in approximately 1 billion years. That’s the good news. The bad news is that once that happens the planet will become completely inhospitable for complex aerobic life.

## What year will humans go extinct?

Humanity has a 95% probability of being extinct in 7 800 000 years according to J. Richard Gott’s formulation of the controversial Doomsday argument which argues that we have probably already lived through half the duration of human history.

## How long have humans existed?

Approximately 300 000 years ago the first Homo sapiens — anatomically modern humans — arose alongside our other hominid relatives.

## Who was the first human on earth?

The First Humans

One of the earliest known humans is Homo habilis or “handy man ” who lived about 2.4 million to 1.4 million years ago in Eastern and Southern Africa.

## What was on Earth before dinosaurs?

At the time all Earth’s land made up a single continent Pangea. The age immediately prior to the dinosaurs was called the Permian. Although there were amphibious reptiles early versions of the dinosaurs the dominant life form was the trilobite visually somewhere between a wood louse and an armadillo.

## How did animals get on earth?

Genetic data suggest that multicellular animals evolved around 1000 million years ago this is supported by fossil embryos from rocks in China that date back 600 million years. … Whatever their origins animals may have ventured onto land early in the Cambrian.

## What if the moon exploded?

If the moon exploded the night sky would change. We would see more stars in the sky but we would also see more meteors and experience more meteorites. The position of the Earth in space would change and temperatures and seasons would dramatically alter and our ocean tides would be much weaker.

## Where is super Earth located?

In 2019 NASA’s Transiting Exoplanet Survey Satellite (TESS) discovered a super-Earth and two mini-Neptunes orbiting a faint cool star about 73 light-years away in the southern constellation of Pictor.

## Who discovered Earth hangs on nothing?

## What 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.

## Are we getting closer to the sun?

We are not getting closer to the sun but scientists have shown that the distance between the sun and the Earth is changing. The sun shines by burning its own fuel which causes it to slowly lose power mass and gravity. … As the sun loses its momentum and mass the Earth can slowly slip away from the sun’s pull.

## What would happen 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.
