228011 (2007 RB288) is a mid-sized asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified 2007 RB288 as potentially hazardous because its orbit does not bring it close to Earth.
2007 RB288 orbits the sun every 4,560 days (12.48 years), coming as close as 5.18 AU and reaching as far as 5.59 AU from the sun. Based on its brightness and the way it reflects light, 2007 RB288 is probably between 6.525 to 14.589 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the San Francisco Bay.
2007 RB288's orbit is 4.19 AU from Earth's orbit at its closest point. This means that there is an extremely wide berth between this asteroid and Earth at all times.
Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.
2007 RB288's orbit is determined by observations dating back to Aug. 29, 1995. It was last officially observed on Jan. 24, 2023. The IAU Minor Planet Center records 558 observations used to determine its orbit.
