How to get coordinates near to specific coordinate using rails?

I have a RoR app which has a feature allowing users to add markers in a google maps. This markers are saved in a model that have latitude and longitude attributes.

Supposing that an user placed and saved a marker in a specific location, Stonehenge for example, how can I verify if have any other markers in 250 meters radius of Stonehenge?

Any help will be really appreciated! Thanks everyone!

Look into the geocoder gem. It can convert addresses to lat/lon and ties into active record to do "find me things near this thing" queries.
