You might want to ask your teacher about that again :-)
If a star is one lightyear away, it takes its light
one year to get to earth. That's the
definition of a lightyear -- the distance light travels in one year.
Now here's a true fact: The light from the sun takes more than eight minutes to reach earth. In other words, we see the sun the way it was more than eight minutes in the past.
