HD 110067 is 105 light-years from the Sun. The NASA Exoplanet Archive lists 6 planets around this K0.0 V star; the first was found in 2023 by transit (Multiple Observatories).
Fly there in 3DHD 110067 b goes round its star every 9.11 days, 10 times as often as Mercury goes round the Sun.
HD 110067 is one of 3 stars in its system: HD 110067 B drawn from the Washington Double Star Catalog; the position of one more star is not catalogued, so it is not 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.
