How many light seconds away is the sun?

How many light seconds away is the sun?

It takes 499.0 seconds for light to travel from the Sun to the Earth, a distance called 1 Astronomical Unit.

How far from the Milky Way galaxy would the Andromeda galaxy be on this scale?

Local Group (a cluster of about 20 galaxies, including the Milky Way) Millions of light-years The Andromeda galaxy is about 2.2 million light-years away from our Milky Way galaxy.

How many arcseconds are in a full circle express your answer using four significant figures?

There are 360×60×60 = 1296000 arcseconds in a full circle.

Could you use the same scale to represent the distances to nearby stars why or why not?

Could you use the same scale to represent the distances to nearby stars? Why or why not? No, the nearest stars would not fit on Earth with this scale. 10 billion light years away.

How long is 1 second in light speed?

The speed of light traveling through a vacuum is exactly 299,792,458 meters (983,571,056 feet) per second. That’s about 186,282 miles per second — a universal constant known in equations as “c,” or light speed.

How long does it take to travel 1 light second?

Light can travel at a speed of 300,000 km (186,000 miles) a second. That means that in one second, light travels the distance you would cover if you traveled around Earth 7.5 times! The moon is about one light second away.

What is the heaviest galaxy?

Located almost a billion light-years away, IC 1101 is the single largest galaxy that has ever been found in the observable universe. Just how large is it? At its largest point, this galaxy extends about 2 million light-years from its core, and it has a mass of about 100 trillion stars.

Is Milky Way or Andromeda bigger?

Most Messier objects are star clusters or gas clouds in our Milky Way galaxy. But the Andromeda galaxy is a whole separate galaxy, even bigger than our Milky Way. In a dark sky, you can see that it’s big on the sky as well, a smudge of distant light larger than a full moon. View at EarthSky Community Photos.

How long would it take Voyager 1 to reach Andromeda?

… and even if we ignored that – it would need 3.3 billion years for the journey at the current distance.

What distance is 1 arc second?

At the equator, an arc-second of longitude approximately equals an arc-second of latitude, which is 1/60th of a nautical mile (or 101.27 feet or 30.87 meters).

How many arcseconds are in 1?

There are 3600 arcseconds in 1 degree.

How many arcseconds are there in a light year?

Problem 1 – If an angular size of 200 arcseconds corresponds to 1 light year at a distance of 1000 light years.

How far away is the nearest star in light years?

Alpha Centauri A & B are roughly 4.35 light years away from us. Proxima Centauri is slightly closer at 4.25 light years.

How far away is the closest star in light years?

The closest star, Proxima Centauri, is 4.24 light-years away. A light-year is 9.44 trillion km, or 5.88 trillion miles. That is an incredibly large distance. Walking to Proxima Centauri would take 950 million years.

How far is 1 light year?

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 fast does light travel 1 mile?

Logic: When light travels at its normal speed of 186,000 miles/second, you see the broadcast immediately. You could be 1 mile or 3,000 miles away from the concert — it doesn’t matter! Why? Light can travel distances very rapidly.

How do you calculate light second?
