MASCARA-4 is 557 light-years from the Sun. The NASA Exoplanet Archive lists 1 planet around this A7 V star; the first was found in 2020 by transit (Multiple Observatories).
Fly there in 3DMASCARA-4 b goes round its star every 2.82 days, 31 times as often as Mercury goes round the Sun.
MASCARA-4 is one of 2 stars in its system. The position of the other star is not catalogued, so only MASCARA-4 and its planets are drawn.

Values are the NASA Exoplanet Archive’s composite parameters. A radius marked estimated comes from a mass–radius relation; a mass marked minimum is M sin i. Planet sizes and colours in the 3D view are renderings: none of these worlds has been photographed as more than a point of light.
