one billion light years = 5.87849981 × 1021 miles
130 billion trillion.
8 billion light years means that the light has taken 8 billion years to reach you. That's how far into the past you are seeing.
222 billion miles = 0.0377647371 light years.
1,000,000,000 light-years (one billion light-years) are in one Gly
A light year is a measure of distance, not time. It is the distance light travels in a year.
To convert miles to light-years, we first note that one light-year is approximately 5.88 trillion miles. Therefore, to find how many light-years are in 3.6 billion miles, we divide 3.6 billion by 5.88 trillion. This calculation shows that 3.6 billion miles is about 0.00061 light-years, or roughly 0.61 milliliters.
Much less than one light year. 5 billion miles is "only" about 0.000850557142 light years.
Pluto's average distance from the sun is about 39.5 astronomical units, which is roughly 3.67 billion miles (5.91 billion kilometers) away. In terms of light years, this distance is approximately 0.0006 light years.
Don't even try it. That is why we use light years to calculate distance. Your calculator will melt if you try.
A billion years equals a billion years. 1,000,000,000 years
1.5 billion stars per 1000 light years.
