#4.2xx10^(-5)# light years

The solar system's distances are not adequately measured in light-years; a light-year is an enormous unit of measurement.

At most 400 million kilometers, and possibly as little as 55 million kilometers, separate Earth and Mars from one another.

The link to the Wikipedia article about Mars

Despite the greater distance we would achieve:

#(400xx10^6 km )/(300000 km//s)~1333s #, which is about 22 minutes. So Mars can be at the most 22 light-minutes from the Earth.

Still, this is your response:

Simply divide the amount of time in seconds that light takes to travel from Earth to Mars by the total number of seconds in a year.

#1333/(365.25xx24xx60xx60)=4.2xx10^(-5)# light years

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
