HD 73344 is 115 light-years from the Sun. The NASA Exoplanet Archive lists 3 planets around this F6 V star; the first was found in 2024 by transit (K2).
Fly there in 3DHD 73344 b goes round its star every 15.6 days, 6 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.
