41555

41555 is a designation that appears in various contexts, most notably as a **NASA Space Act Agreement** identifier for a small asteroid. Officially named **2000 PH5**, the object was discovered on August 1, 2000, by astronomers at the Lincoln Near-Earth Asteroid Research (LINEAR) program in New Mexico. The designation "41555" was later assigned as part of NASA’s cataloging system for near-Earth objects (NEOs) under the Space Act Agreement, which facilitates collaboration between the agency and external partners for planetary defense and scientific research.

2000 PH5 (41555) is classified as an Apollo-type asteroid, meaning its orbit crosses that of Earth. It has an estimated diameter of approximately 1.5 kilometers (0.93 miles) and an orbital period of about 3.2 years. While it is not currently considered a significant threat to Earth, its trajectory is monitored as part of NASA’s efforts to track potentially hazardous objects. The asteroid’s designation reflects its place in the broader catalog of NEOs studied for both scientific and safety reasons.

Beyond astronomy, "41555" has also been referenced in other contexts, such as numbering systems in databases, software identifiers, or even niche communities. However, its most recognized use remains within planetary science, where it serves as a key entry in NASA’s NEO database. The object continues to be studied to better understand its composition, orbital dynamics, and potential long-term risks to Earth.
