18054 (1999 SW7) is a large asteroid that shares Jupiter's orbit around the sun. NASA JPL has not classified 1999 SW7 as potentially hazardous because its orbit does not bring it close to Earth.
1999 SW7 orbits the sun every 4,390 days (12.02 years), coming as close as 5.15 AU and reaching as far as 5.35 AU from the sun. 1999 SW7 is about 36.2 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Houston.
1999 SW7's orbit is 4.15 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.
1999 SW7's orbit is determined by observations dating back to Dec. 16, 1955. It was last officially observed on May 2, 2023. The IAU Minor Planet Center records 2,620 observations used to determine its orbit.
