HAT-P-16 is 739 light-years from the Sun. The NASA Exoplanet Archive lists 1 planet around this F8 star; the first was found in 2010 by transit (HATNet).
Fly there in 3DHAT-P-16 b goes round its star every 2.78 days, 32 times as often as Mercury goes round the Sun.
HAT-P-16 is one of 3 stars in its system: HAT-P-16 B drawn from the Washington Double Star Catalog; the position of one more star is not catalogued, so it is not drawn.

HAT-P-16 B has no spectral type listed of magnitude 15.1, judged a true companion. In 2013 it was 0.7″ from HAT-P-16, at position angle 154° (Washington Double Star Catalog, 00383+4228 HTP 16): 159 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-16 b | 2.78 days | 0.0413 AU | 14.684 R⊕ | 1341.6 M⊕ | Transit, 2010 |
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.
