135138

135138 is an asteroid that was discovered on October 15, 2001, by the Lincoln Near-Earth Asteroid Research (LINEAR) project. It is classified as a near-Earth object (NEO) and a potentially hazardous asteroid (PHA) due to its size and proximity to Earth's orbit. The asteroid has an estimated diameter of approximately 1.3 kilometers (0.81 miles) and orbits the Sun every 1.3 years. Its orbit brings it close to Earth, with a minimum orbital intersection distance (MOID) of 0.016 astronomical units (AU), which is less than the distance between Earth and the Moon. Despite its classification as a PHA, 135138 poses no immediate threat to Earth, and its orbit is well understood. The asteroid is named after the LINEAR project, which has discovered thousands of NEOs since its inception in 1998.
