# Triangulating Sol's position from another star

Let me pose this question as a hypothetical.

Your ship makes a warp/jump through space. There's a malfunction. You're definitely not at your intended destination. You've warped to an unknown star, but you have managed to land you and your crew on a habitable planet orbiting this star. Survival is not an issue.

You need to know where Earth is. How would you go about triangulating Sol's position?

What tools and knowledge would you need?

• You need the information stored in the voyager which describe the position of Sol relative to known pulsars (I think). This was exactly the problem Carl Sagan was trying to solve when he inscribed the gold disks riding on Voyager. – John Alexiou Sep 22 '18 at 15:01
• @ja72 Only works if we are in the local vicinity, Galactically speaking. – Rob Jeffries Sep 22 '18 at 15:18
• and for only the next $10^5$ years, given a typical lifetime of the pulsar phenomenon. – Rob Jeffries Sep 24 '18 at 6:08
