Seeing TRAPPIST-1 b in real time

TRAPPIST-1 b is placed at its true position on the sky and at its real measured distance, not as a flat backdrop. Fly out from the Sun in the live 3D view and watch it change from a point of light into structure as you approach, with the scale bar showing just how far out you have travelled.
