How far away is 1 light-year in km?

How far away is 1 light-year in km?

Light-year is the distance light travels in one year. Light zips through interstellar space at 186,000 miles (300,000 kilometers) per second and 5.88 trillion miles (9.46 trillion kilometers) per year.

How long will it take to travel 1 billion light-years?

If your spacecraft could travel at 1% of the speed of light, or about 3,000 km/second, it would take you: 300,000 / 3000 x 1 billion light years ==100 billion years to travel a distance of 1 billion light years.

How many kilometers in 1 billion?

A gigametre = 1 billion metres (or 1,000,000Km)

How long is 1 light-year in Earth years?

Since light travels at about 186,300 miles per second, with 86,400 seconds per day and about 365 days per year, that works out at about: 186300×86400×365≈5,875,000,000,000 miles.

Can we travel 1 light-year?

This duration is a bit of a problem, as it makes space exploration a painstakingly slow process. Even if we hopped aboard the space shuttle discovery, which can travel 5 miles a second, it would take us about 37,200 years to go one light-year.

How far is 500 million light-years?

Therefore there are 2939312686591800000000 miles in 500 million light years. If we can write in another way the answer will be, There is 2939×1021 a mile in 500 million light years.

What is beyond the universe?

The trite answer is that both space and time were created at the big bang about 14 billion years ago, so there is nothing beyond the universe. However, much of the universe exists beyond the observable universe, which is maybe about 90 billion light years across.

How big is the Milky Way?

How can we see past 13 billion light years?

We know that light takes time to travel, so that if we observe an object that is 13 billion light years away, then that light has been traveling towards us for 13 billion years. Essentially, we are seeing that object as it appeared 13 billion years ago.

How does 1 billion look like?

If you write a 1 followed by nine zeros, you get 1,000,000,000 = one billion! That’s a lot of zeros!

How much is 100 crore in billion?

In terms of crores, 1 billion is equivalent to 100 crores, i.e. 1 bn (1 b) = 1,000,000,000.

Why is it called 1 billion?

According to the Oxford English Dictionary, the word billion was formed in the 16th century (from million and the prefix bi-, “two”), meaning the second power of a million (1,000,0002 = 1012). This long scale definition was similarly applied to trillion, quadrillion and so on.

How many human years are in a Lightyear?

How many light-years is the Milky Way?

Our galaxy probably contains 100 to 400 billion stars, and is about 100,000 light-years across.

How fast speed of light is?

Light from a stationary source travels at 300,000 km/sec (186,000 miles/sec).

Is it Dark in space?

Since there is virtually nothing in space to scatter or re-radiate the light to our eye, we see no part of the light and the sky appears to be black.

Is anything faster than the speed of light?

So, according to de Rham, the only thing capable of traveling faster than the speed of light is, somewhat paradoxically, light itself, though only when not in the vacuum of space. Of note, regardless of the medium, light will never exceed its maximum speed of 186,282 miles per second.

Does time stop at the speed of light?

If you were able to travel at the speed of light, all of your motion would be wrapped up in getting you to travel at the maximum speed through space, and there would be none left to help you travel through time — and, for you, time would stop. At the speed of light, there is no passage of time.

Is light-year bigger than km?

A light-year, alternatively spelled light year, is a large unit of length used to express astronomical distances and is equivalent to about 9.46 trillion kilometers (9.46×1012 km), or 5.88 trillion miles (5.88×1012 mi).

How far away is 100000 light-years?

Distance Information The Milky Way is about 1,000,000,000,000,000,000 km (about 100,000 light years or about 30 kpc) across. The Sun does not lie near the center of our Galaxy. It lies about 8 kpc from the center on what is known as the Orion Arm of the Milky Way.

How long is a second in light-years?

The light-second is a unit of length useful in astronomy, telecommunications and relativistic physics. It is defined as the distance that light travels in free space in one second, and is equal to exactly 299792458 metres (983571056 ft).

How long would it take to travel 1 light-year in a car?

How long would it take a car to travel one light year? Easy. A light year is about 10 trillion kilometers and a typical highway speed is 100 kilometers an hour (62 mph). So you’re talking 100 billion hours, or 11.4 million years.
