. That is not mear, but a much larger distance.
Sorry John,
You are just a little off there
Light travels at 186,000 miles per second
60sec X 60min X 24hrs X 365 days = 1 year X 186,000 =
1,818,371,625,696,000,000 or roughly 1.818 Quintillion miles in a light year
Then by 35 million
63,643,006,899,360,000,000,000,000 or roughly 63.646 Septillion miles
Our fastest probe is traveling at 40,850 mph X 24hrs X 365 days
It covers 357,846,000 miles per year
At that rate, it would take
177,850,267,711,138,310.89 roughly 177.85 Quadrillion years to reach it.
