LOS ANGELES — Apparently astronauts are no match for Jackass.

Paramount’s “Jackass Presents: Bad Grandpa” topped the weekend box office with $32 million, according to studio estimates Sunday, sinking three-week champ “Gravity” to second place.

“Bad Grandpa” stars Johnny Knoxville as an accident-prone grandfather in a hidden-camera comedy a la “Borat.”

“It’s been a very heavy fall in terms of the content of the movies, so I think audiences were ready for something completely lighthearted and out of left field,” said box-office analyst Paul Dergarabedian of Rentrak.

“Gravity,” which stars Sandra Bullock and George Clooney as astronauts on a troubled spacecraft, has soared since its debut three weeks ago. The Warner Bros. space adventure added another $20.3 million to its haul over the weekend, bringing its domestic ticket totals to nearly $200 million.

1. “Jackass Presents: Bad Grandpa,” $32 million.

2. “Gravity,” $20.3 million.

3. “Captain Phillips,” $11.8 million.
