Key Facts

Overview

233P/La Sagra is a large comet whose orbit brings it closer to the sun than Jupiter. NASA JPL has not classified 233P/La Sagra as potentially hazardous because its orbit does not bring it close to Earth.

233P/La Sagra orbits the sun every 1,930 days (5.28 years), coming as close as 1.79 AU and reaching as far as 4.28 AU from the sun. Based on its brightness and the way it reflects light, 233P/La Sagra is probably between 2658.000 to 5943.469 kilometers in diameter, making it the largest asteroid/dwarf planet, very roughly comparable in size to the U.S. state of Alaska.

No Close Approaches

233P/La Sagra's orbit is 0.82 AU from Earth's orbit at its closest point. This means that there is an very 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.

Images and Observations

233P/La Sagra's orbit is determined by observations dating back to Feb. 9, 2005. It was last officially observed on Feb. 18, 2010. The IAU Minor Planet Center records 62 observations used to determine its orbit.

Accessibility and Exploration

This comet is not considered a viable target for human exploration by the NHATS study.
