A light year is how far light travels in a year. A light min is how far light travels in a minute.
light speed is 186000 mile/sec, at this speed you have to calculate how far it would travel in one year or one minute

A light year is the distance light travels in one year, approximately 9.46 trillion kilometers. In contrast, a light minute is the distance light travels in one minute, which is about 17.99 million kilometers.
If you mean in a year then that's about the length of time in a year and that's why we have an extra day each leap year.
It takes about 8 minutes and 20 seconds for light to travel from the sun to the Earth, which is about 93 million miles away.
The Earth will not burn up from the sun. The sun will continue to expand in about 5 billion years, eventually engulfing the Earth and making it uninhabitable.
Minutes are a unit of time, not of distance. Perhaps you mean LIGHT minutes, which refer to the distance light travels in a minute. Earth is 1 AU from the sun, which takes light about 8 minutes and 20 seconds. Mars is about 1.5 AU, so when earth and Mars are on the same side of the sun, the distance between them is 0.5 AU. Light would take four minutes, 10 seconds to cross that gap. When Mars and Earth are on opposite sides of the sun, the distance between them is 2.5 AU, which would take light nearly 21 minutes to cross. On average, Earth and Mars would be at roughly right angles to the sun, so you could use the Pythagorean theorem to calculate the distance of their hypotenuse: About 1.8 AU. I'll leave the conversion of this into light time as an exercise for the gentle reader.
it is 8 minutes and 33 seconds To reach the sun at light speed which is 1AU away appx 92-94 million miles away light travels at 186,000 miles a second. 186,000*60=11,160,000 miles a minute 92,000,000/11,160,000=8.2437 min 94,000,000/11,160,000=8.4229 min 8.2437+8.4229=16.6666/2=8.33 min is the mean time for light to reach the sun from earth or earth to the sun.
