Answer:
-- The nearest one is about 93 million miles away. That's the one called the "Sun".
-- The next nearest one is in the constellation Centaurus. It's about 4.2 light years away.
That's about 24,691,000,000,000 miles.
-- The farthest ones that can be detected by today's best astronomical equipment
are about 14 billion light years away.
That would be around 82,302,000,000,000,000,000,000 miles.
