2211340

2211340 is a notable astronomical object identified by its minor planet designation. It was discovered on October 10, 2003, by the Lincoln Near-Earth Asteroid Research (LINEAR) project, which is operated by the Massachusetts Institute of Technology Lincoln Laboratory and the U.S. Air Force. The object is classified as a near-Earth object (NEO) and a potentially hazardous asteroid (PHA) due to its size and proximity to Earth's orbit.

2211340 has an estimated diameter of approximately 1.1 kilometers, making it one of the larger known PHAs. Its orbit intersects with Earth's orbit, and it has been observed to approach Earth at relatively close distances. The closest approach of 2211340 to Earth occurred on October 10, 2003, when it passed within about 0.05 astronomical units (AU) of our planet. Despite its potential hazard, 2211340 is not expected to impact Earth in the foreseeable future.

The study of 2211340 and other PHAs is crucial for understanding the dynamics of the solar system and for developing strategies to mitigate potential impacts from these objects. Ongoing observations and research continue to refine our knowledge of 2211340's orbit and its long-term behavior.
