216 Kleopatra

216 Kleopatra is a fascinating asteroid in our Solar System that has captured the attention of astronomers and space enthusiasts alike. Positioned at an average distance of 4.18e+8 km (2.793 AU) from the Sun, 216 Kleopatra occupies a significant place in the Solar System's architecture. As an asteroid, 216 Kleopatra represents the remnants of the early Solar System, providing valuable insights into the formation and evolution of our cosmic neighborhood.

The 216 Kleopatra physical characteristics reveal a world of remarkable dimensions and properties. The 216 Kleopatra mass of 3.00e+18 kg represents 1990666.7× smaller than Earth's mass, giving this world substantial gravitational influence.

The 216 Kleopatra orbit reveals fascinating details about its journey around the Sun and its relationship to other Solar System objects. The 216 Kleopatra orbit has a semimajor axis of 4.18e+8 km (2.793 AU), placing it 2.8× Earth's distance from the Sun. At its closest approach (perihelion), 216 Kleopatra comes within 3.13e+8 km of the Sun, while at its farthest point (aphelion), it reaches 5.23e+8 km, creating a 50.4% variation in solar distance. The 216 Kleopatra orbit is moderately elliptical with an eccentricity of 0.252 (15.1× Earth's orbital eccentricity), creating noticeable seasonal variations in solar radiation. The 216 Kleopatra orbit takes 0.47 hours to complete (18487.5× smaller than Earth's orbital period), defining the length of its year. The orbital inclination of 13.099° indicates how much the 216 Kleopatra orbit is tilted relative to the Solar System's ecliptic plane. This moderate inclination indicates a typical orbital evolution for objects in this region of the Solar System.

The 216 Kleopatra rotation and axial orientation provide crucial insights into its daily and seasonal cycles, as well as its orbital dynamics. The 216 Kleopatra axial tilt of 0° determines the intensity and nature of seasonal variations. With minimal axial tilt, 216 Kleopatra experiences virtually no seasonal changes, maintaining relatively constant temperatures throughout its year. The orbital orientation parameters reveal additional details about 216 Kleopatra's position in space. The mean anomaly of 0° indicates the planet's current position in its orbit relative to its perihelion. The argument of periapsis of 0° shows how the orbit's orientation changes over time due to gravitational perturbations. The longitude of ascending node of 0° defines the reference point where the orbit crosses the ecliptic plane.

The 216 Kleopatra temperature and atmospheric conditions are fundamental to understanding its habitability and environmental characteristics. The 216 Kleopatra average temperature of 0.0 K (-273.1 °C) (-459.7°F) provides the baseline for understanding its climate. These extremely cold temperatures make 216 Kleopatra inhospitable to life as we know it, with any atmosphere likely frozen solid on the surface. Compared to Earth's average temperature of 15°C (59°F), 216 Kleopatra presents a dramatically different thermal environment. Being farther from the Sun than Earth, 216 Kleopatra receives less solar radiation, resulting in cooler conditions. The elliptical orbit creates significant temperature variations throughout the year, with extreme seasonal changes.

The 216 Kleopatra escape velocity and shape characteristics reveal important details about its gravitational field and rotational dynamics. The 216 Kleopatra escape velocity of 0 m/s determines how easily objects can break free from its gravitational pull. This relatively low escape velocity means that gases and light molecules can easily escape into space, making it difficult for 216 Kleopatra to retain a substantial atmosphere. The 216 Kleopatra flattening of 0.0000% indicates how much the planet's rotation affects its shape. This minimal flattening suggests a nearly spherical shape, indicating either slow rotation or a very rigid internal structure.
