1 Astronomical Unit = ~8.32 light minutes
1.5 AU
Light travels 1 AU in about 8 minutes 20 seconds (8.33 minutes). Therefore 8.4 AU takes about 8.4 x 8.33 minutes. That's 69.97 minutes. So, the answer is: about 70 minutes, or an hour and ten minutes.
Very nearly a light year, since a light year is 63,239.6717 AU. That's very nearly the same ratio as the difference between an inch and a mile (a factor of 63,360). "Give 'em an AU, they'll take a light year."An AU or astronomical unit is the average distance between the Earth and the sun. It is a unit used to measure distances within the solar system. A light year is the distance light travels in a year and is much larger than an AU. Light years are used to measure distances between stars and galaxies. A light year is about 63,000 AU.
Ceres is less than 5 AU from the sun, an AU being an Astronomical Unit. The equivalent of one AU is 93.000.000 miles, or 149.668.992 kilometers, so about 465.000.000 miles, or 748.344.960 kilometers!
One AU is 148,597,871 km, so 0.7 AU is 104,718,510 km. The velocity of light and other electromagnetic radiations in free space is 299,792.458 km/second, so the time for the round trip is (2 * 104,718,510 / 299,792.458) seconds - or 698.6 seconds (11 minutes, 38.6 seconds.)
They really are not comparable. Light travels 186,000 miles per second, and one AU is about 8.3 light-MINUTES. You can probably do the math, from minutes to hours to days to years as well as I can. Or, you could google "1000 light years in AU" and get the answer
That's about 0.72 AU.
On average Uranus is about 19.2 AU from the Sun, this equates to about 160 light minutes or 2.6 hours
1.5 AU
A light year is much bigger, an AU is only about 8 light minutes.1 light year = 63,240 AU
Light travels 1 AU in about 8 minutes 20 seconds (8.33 minutes). Therefore 8.4 AU takes about 8.4 x 8.33 minutes. That's 69.97 minutes. So, the answer is: about 70 minutes, or an hour and ten minutes.
1 AU = 0.0000158 light-years
It takes light about 8 minutes to reach Earth, so you could use that or just ask google to get 63239.7263
1 AU is approximately 8 light minutes.
600 light-years is 37,944,646.2 AU
2.25 AU
Mars has an orbit which varies its distance from the sun from 1.38 AU to 1.66 AU but it's semi-major axis is 1.52 AU.. so in other words.. Yes
