##### In a car, how long would it take to drive to Neptune?

Ok, we all know that the universe is huge. We all know, for that matter, that our solar system is huge.
But just to put it in perspective: How long would it take for a car traveling at 100 kph (starting at the center of the sun) to reach the end of the solar system (Neptune’s orbit?).

[MOD EDIT - Emilio, please can you format your posts' titles as questions, which is the accepted forum policy. Thank you. Chris]

Neptune is about 4.5 billion k's from the centre of the Sun.

Better take some sandwiches with you on that trip!

So 4 500 000 000/100 gives 45 000 000 hours which is around 5137 years!

NASA's "new horizons" mission to Pluto is going to take about a decade to get there.

The craft is currently between the orbits of Saturn and Uranus, travelling at approx 60,000 Kph...

Why start from the centre of the Sun ?, start from the surface not so hot and not so far to go.

I assume you'll be taking a Ford Galaxy.

Mitsubishi Starion ?

Quote
The "Starion" name is claimed to be a contraction of "Star of Orion."
It was also widely believed that the Japanese intended the name to be "Stallion",
but due to lack of "l" in Japanese, the name was spelled with "r" instead .
