I cannot find out how far from earth Starman of the Falcon Heavy is right now, or at any time for that matter. How would I find the distance?
I've created a website to tell this information. It isn't perfect, but it is mostly accurate, at least for now. http://www.whereisroadster.com/ As of editing this post,
The current location is 1,297,260 miles (2,087,737 km, 0.014 AU) from Earth, moving away from Earth at a speed of 6,862 miles/hour (11,043 km/hour, 3.07 km/s).
The information comes from JPL/Horizons, which used SpaceX's ephemeris as well as visual observations to model it's path for some time.
You can track it use this number
Those orbital elements refer to the parking orbit prior to the burn that took it out of earth orbit. The parking orbit was approximately 180 x 6951 km, and it completed two orbits before executing the burn at about 0230 UTC on 7 Feb 2018 just before the second perigee (where it was most energy-efficient to do so). We observed this visually in San Diego during a pass just after local sunset.
NORAD does not maintain elements for objects not in earth orbit but NASA JPL does. You can locate Starman/Tesla/FH through their Horizons online system: horizons.jpl.nasa.gov. It's designed for solar system objects.
