HIP 57274 is 84.3 light-years from the Sun. The NASA Exoplanet Archive lists 3 planets around this K4 V star; the first was found in 2011 by radial velocity (W. M. Keck Observatory).
Fly there in 3DHIP 57274 b goes round its star every 8.14 days, 11 times as often as Mercury goes round the Sun.

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.
