If something in space is 10 light years away, we would only observe it as it was 10 years ago, as this is the time light has taken to reach us.
A light year is a distance not a time. It is the distance that light travels in a year (about 5865696000000 miles or 9385113600000 Kilometres) so you cannot ask how long ago is 10 light years away. That would be the same as asking how long ago is the bus station away.

Well, let's see: Speed of light = 300,000,000 meters/sec 1 minute = 60 sec Lightspeed x 60 sec = (300,000,000 x 60) = 18,000,000,000 meters = 18 million km = 11,177,000 miles.
Light travels at approximately 186,282 miles per second, which equates to about 5.88 trillion miles in a year (1 light year). In minutes, light travels approximately 186,282 miles in just one second.
Ten minutes is a measure of time. Light years are a measure of distance. Ten minutes cannot be expressed in light years.
These are not comparable. A light-year is a measure of distance, the distance that light travels in one year.
A minute is a measure of time.
A light year is a measurement of distance, not time. It is the distance that light travels in a year. It is about 5,869,713,600,000 miles or about 9,445,950,434,502 kilometres.
The comparison doesn't make sense, since a light-year is a unit of distance, and a minute is a unit of time.
The distance light travels in a year is called light-year
-Light travels at 299,792,458 meters per second.-There is 31,556,926 seconds in one year.-Light travels 9,460,528,412,464,108 meters in one year and after doing the math, light travels 9,460,528,412,464.108 kilometers in one year.
"light-year"
9,460,730,472,580.8 km Light travels at 299,792.458 km/sec. There are 60 seconds in a minute, 60 minutes in an hour, 24 hours in a day, and 365.24 days in a year. Multiply all those together to get the distance that light travels in one year.
Earth orbits the sun in about 1 year, not light years. A light year is the distance light travels in a year, approximately 9.46 trillion kilometers. Earth's orbit around the sun is much smaller in comparison, about 150 million kilometers.
