How many light years would it take to reach the sun?

Answer 1

It would not take any light-years to reach the sun. The sun is much closer than a light year. It is only about 92 million miles or 148 million km away. That works out to roughly 8 light minutes and 20 seconds.

Answer 2

Depends on the definition of the boundary of the Solar System

Anywhere between 0.0031 and 2 years for light to travel from the inner solar system to the boundary; twice that to travel from one edge across to the opposite edge.

Answer 3

That would totally depend upon the speed you are traveling. The Voyager is about 11 billion miles away from the earth right now. Assume you mean from the center of the solar system which would be 93 million miles from earth then it is about 11.1 billion miles from the center of the solar system to the outer edge of the solar system. The voyager is traveling about 38,400 miles and hour. So we'll do the math from there. 11.1 billion divided by 38,400 mph =

28756 hours divided by 24 hours will tell you how long it would take. It would take about 1198 days to get from the center (the sun) to the edge at that speed according to my calculations. We can not travel any faster than that at this time.

Answer 4

The average diameter of Pluto's orbit is something like 11,750 million km. In order to cross from one side of it to the other, straight through the sun, at the speed of light, you're talking about a trip of something like 10.9 hours.

Really stretching it out to include the Kuiper belt and the Oort cloud, you can double that.

All in all, to cross the diameter of the sun's influence at the speed of light means maybe a day's travel. And then there's nothing at all for the next 4.3 years, until you reach the neighborhood of the next nearest star . . .

Answer 5

That depends what you define as the outer limit of the Solar System: (a) the last known planet? (b) the area where the solar wind becomes insignificant? (c) the Oort Cloud? The Oort cloud is estimated to be at a distance of 1 light-year from the Sun, so that would make 2 light-years across. Using other criteria, the Solar System is much smaller.

Answer 6

The sun is about 93 million miles away from Earth. In terms of light years, this distance is equivalent to about 0.0000158 light years. Traveling at the speed of light, it would take about 8 minutes and 20 seconds to reach the sun.

Answer 7

The diameter of the solar system is approximately 7,500,000,000 miles and light travels 5,865,696,000,000 miles in a year, so the diameter of the solar system is about 0.0013 light years.

Answer 8

Pluto is only about 5 1/2 light HOURS from the sun.
