![The separation of β Pictoris b and β Pictoris c from the star in terms of their Hill sphere. β Pictoris b has a longer orbital period (∼20 yr), with a Hill sphere primary transit at MJD ∼58000 and a Hill sphere radius of 1.1 au. β Pictoris c has a shorter orbital period (∼3.3 yr), with two primary transits at MJD 58195+11 −20 and 59415+8 −8 and a secondary transit at 58707+3 −7 . The § Hill sphere radius is approximately 0.3 au. -- [astro-ph.EP]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/09/The-Hill.png?resize=1200%2C712&ssl=1)
