18931993
18931993 is a notable astronomical object classified as a minor planet, also known as an asteroid. It was discovered on October 2, 1973, by astronomers at the Palomar Observatory in California. The asteroid is part of the Apollo group, which are near-Earth asteroids with orbits that can bring them close to Earth's orbit. 18931993 has an estimated diameter of about 1.5 kilometers and completes one orbit around the Sun approximately every 1.2 years. Its orbit is inclined at an angle of about 10 degrees to the ecliptic plane. Due to its proximity to Earth and its relatively large size, 18931993 is considered a potentially hazardous asteroid, although it does not pose an immediate threat of impact. The asteroid's orbit is well-studied, and its trajectory has been calculated to ensure it will not collide with Earth for at least the next century.
