How do we measure distance to galaxies and stars/planets?
Luke AllenPlanets by Radar Near by stars Parallax method. Galaxies Cepheid variables and red shift.
Earth's travel in one year is about 150 million KM. This is taken as base and measure parallax

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.
