After some astronomical news, there is a feeling that you live in a very boring planetary system, while someone can admire the Tatooine sunsets with two suns (more than a dozen such exoplanets are already known) or watch several stars dance in the sky. Recently, the TESS telescope discovered a system in which three pairs of stars revolve around a common center of mass, forming an eclipsing three times double (or is it six-fold?) Star.

It consists of three star pairs. In each pair, the heavier star is slightly larger and brighter than our Sun and has a slightly higher temperature. The lighter star is about half the size of the Sun and shines three times fainter. These pairs rotate relative to each other with periods from 1.3 to 8.2 days. The two pairs form two centers of mass that revolve around each other with a period of slightly less than 4 years. And finally, a third pair orbits around these two pairs, making a revolution in two thousand years.
