Two stars of about 6,200 K and 3,100 K (2.1 and 1.3 times the Sun's radius, ~1.2 and ~0.6 solar masses) orbit each other every 21.3 hours, 3.3 million km apart (the Sun-Mercury distance is 58 million km). We see the orbit at 50 degrees (90 = exactly edge-on), close enough to edge-on that they eclipse each other. Sizes, separation, tilt and colours come from fitting the TESS eclipses (see the model-fit plot) plus Gaia's temperature; masses assume normal main-sequence stars. Surface texture, glowing halos, the viewpoint and the background are artistic. The secondary eclipse arrives 64 minutes earlier than half an orbit after the primary, a sign of a slightly oval (eccentric) orbit: e*cos(omega) = -0.0785.","tic":"156892633","title":"TIC 156892633","tmag":"8.87","type":"Transit candidate"}
