KELT-3 is 686 light-years from the Sun. The NASA Exoplanet Archive lists 1 planet around this 6,304 K star; the first was found in 2013 by transit (KELT).
Fly there in 3DKELT-3 b goes round its star every 2.70 days, 33 times as often as Mercury goes round the Sun.
KELT-3 is one of 2 stars in its system. The position of the other star is not catalogued, so only KELT-3 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.
