KELT-4 A is 711 light-years from the Sun. The NASA Exoplanet Archive lists 1 planet around this F star; the first was found in 2016 by transit (KELT).
Fly there in 3DKELT-4 A b goes round its star every 2.99 days, 29 times as often as Mercury goes round the Sun.
KELT-4 A is one of 3 stars in its system. The position of the other 2 is not catalogued, so only KELT-4 A 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.
