Curious: what's a significant figure for this placement?
@RiverdaleBoy @NASAWebbTelescp orbital stability in a 3 body system and the Earth doesn’t get in the way as often.
@evilscientistca @NASAWebbTelescp
I meant how close to the theoretical point do they (have to) get?
@RiverdaleBoy @NASAWebbTelescp strictly speaking they’ll be orbiting the L2 point: http://map.gsfc.nasa.gov/mission/observatory_l2.html …
@evilscientistca @RiverdaleBoy We do orbit L2 (as we orbit the Sun). Our orbit is large, about the size of moon's orbit around Earth.
@NASAWebbTelescp @evilscientistca
Once a year. I get that. Is the satellite's period the same?
@NASAWebbTelescp @evilscientistca
Hold on. Maybe I don't get it at all. Better stick to my strengths. Lol
@RiverdaleBoy @evilscientistca This diagram might help you picture it? http://www.stsci.edu/jwst/overview/design/orbit2.jpg …
@NASAWebbTelescp @evilscientistca
It was the "orbiting" of an empty point that threw me. Empty point, no gravitation.
@RiverdaleBoy @evilscientistca The fact that you can orbit empty space there is what makes the L points special. https://en.wikipedia.org/wiki/Halo_orbit
@NASAWebbTelescp @evilscientistca
That clears it up for me. Thanks.
