201355EU

201355EU is a designation assigned to a specific asteroid in the Solar System, cataloged by the Minor Planet Center. The object was first observed on November 29, 2013, by astronomers at the La Sagra Sky Survey in Spain. It belongs to the Apollo group of near-Earth asteroids, which are characterized by orbits that intersect Earth’s path around the Sun, posing a potential (though generally low) risk of collision with our planet.

The asteroid has an estimated diameter of approximately 100 meters (330 feet), based on its absolute magnitude and albedo. Its orbit carries it between the inner and outer edges of the asteroid belt, occasionally bringing it closer to Earth. Observations indicate that 201355EU has an orbital period of around 1.5 years, with a highly elliptical trajectory that varies significantly in distance from the Sun.

While 201355EU is classified as a near-Earth object (NEO), its trajectory has been monitored by space agencies and astronomical organizations to assess any potential future impact risks. Current calculations suggest no imminent threat, but long-term tracking remains essential due to orbital perturbations caused by gravitational interactions with other celestial bodies.

The asteroid’s designation follows the standard naming convention used by the Minor Planet Center, where the year of discovery (2013), a sequential number (55), and the letter "EU" (indicating its half-month of observation) identify it uniquely. Further study of objects like 201355EU helps scientists refine models of near-Earth object dynamics and improve planetary defense strategies.
