K2-136 is 193 light-years from the Sun. The NASA Exoplanet Archive lists 3 planets around this K5.5 star; the first was found in 2017 by transit (K2).
Fly there in 3DK2-136 b goes round its star every 7.98 days, 11 times as often as Mercury goes round the Sun.
K2-136 is one of 2 stars in its system. The position of the other star is not catalogued, so only K2-136 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.
