HAT-P-33 is 1,292 light-years from the Sun. The NASA Exoplanet Archive lists 1 planet around this F4 star; the first was found in 2011 by transit (HATNet).
Fly there in 3DHAT-P-33 b goes round its star every 3.47 days, 25 times as often as Mercury goes round the Sun.
HAT-P-33 is one of 2 stars in its system: the other is drawn where the Washington Double Star Catalog measures it on the sky.

HAT-P-33 B has no spectral type listed of magnitude 13.68, judged a true companion. In 2013 it was 0.3″ from HAT-P-33, at position angle 118° (Washington Double Star Catalog, 07327+3350 HTP 33): 119 AU on the sky at this distance. The true distance can only be larger. Its colour is estimated from its brightness.
| Planet | Year | Orbit | Radius | Mass | Found |
|---|---|---|---|---|---|
| HAT-P-33 b | 3.47 days | 0.0500 AU | 20.737 R⊕ | 292.4 M⊕ | Transit, 2011 |
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.
