What is 30 light years?

Answer 1

The Oort Cloud is believed to be approximately at that distance.

The farthest known planets, and asteroids, in our own Solar System are just a tiny fraction of a light-year away; Neptune has an orbit with a radius of 0.00011 light years. The nearest star outside our Solar System has a distance of about 4.2 light-years.

Answer 2

The speed of Light c = 300,000m/sec. |Seconds per Year| = 3,600 secs/hr * 24 hrs/day = 86,400 sec/day.

Units ALWAYS must and do cancel. 86,400 sec/day * 365.25 days/year = 31,557,600 sec/year. So, 300,000 m/sec * 31,557,600 sec/year = 9,460,000,000,000,000 meters per year - the spatial stretch of a light-year. Compare to 'one AU - astronomical unit'!

Answer 3

There are about 5.88 trillion miles in a light year. So, the answer is: about 5.88 x 1000000000000 x 47000000000 miles, approximately.

That's 5.88 x 47 x 1021 miles = about 2.76 x 1023 miles.

Answer 4

At 5,878,625,373,183.607 miles / 1 light Year you will find the Oort Cloud. Its a distant group of icey and rocky material still caught by the Suns gravity. Many comets are believed to originate from there. There is also the possibilty that there is a Super Giant Planet there called Tyche, with a mass 15 times that of Jupiter.

Answer 6

31 light years equates to about 181.7 trillion miles. This is so far away that even if you were traveling at the speed of light it would still take you at least 31 years to get there.

Answer 7

It is 9 quadrillion 454 trillion 254 billion 955 million 488 thousand (9,454,254,955,488,000) metres away. OR... 94 trillion 542 billion 549 million 554 thousand 880 (94,542,549,554,880) kilometres away. OR... About 5 trillion 874 billion 601 million 671 thousand 792 (5,874,601,671,792) miles away.

Answer 8

Thirty light years is a unit of distance equal to the distance that light travels in 30 years. Light years are commonly used in astronomy to measure distances between stars and galaxies.

Answer 9

30 light years is the distance light would travel in 30 years. According to Google, 30 light years equals 2.838e+17 meters.

Answer 10

the distance light travels in one year. light speed is 3E8 km/sec, so 1 light year is 300,000,000 km long.
