Dimorphos

Dimorphos is a fascinating moon in our Solar System that has captured the attention of astronomers and space enthusiasts alike. Positioned at an average distance of 1 km (0.000 AU) from the Sun, Dimorphos occupies a significant place in the Solar System's architecture. As a moon, Dimorphos demonstrates the incredible diversity of natural satellites that orbit larger celestial bodies throughout our Solar System.

The Dimorphos physical characteristics reveal a world of remarkable dimensions and properties. The Dimorphos mass of 4.84e+9 kg represents 1233629415410039.3× smaller than Earth's mass, giving this world substantial gravitational influence.

The Dimorphos orbit reveals fascinating details about its journey around the Sun and its relationship to other Solar System objects. The Dimorphos orbit has a semimajor axis of 1 km (0.000 AU), placing it 149598023.0× smaller than Earth's distance from the Sun. The Dimorphos orbit is nearly circular with an eccentricity of 0, resulting in relatively stable solar heating throughout its year. The orbital inclination of 0° indicates how much the Dimorphos orbit is tilted relative to the Solar System's ecliptic plane. This low inclination means Dimorphos follows a path very close to the plane where most planets orbit, suggesting a stable formation history.

The Dimorphos rotation and axial orientation provide crucial insights into its daily and seasonal cycles, as well as its orbital dynamics. The Dimorphos rotation period of 0.00 hours (7577.5× smaller than Earth's rotation period) determines the length of its day. This extremely fast rotation creates intense centrifugal forces and may contribute to the planet's flattened shape. The Dimorphos axial tilt of 0° determines the intensity and nature of seasonal variations. With minimal axial tilt, Dimorphos experiences virtually no seasonal changes, maintaining relatively constant temperatures throughout its year. The orbital orientation parameters reveal additional details about Dimorphos'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 Dimorphos temperature and atmospheric conditions are fundamental to understanding its habitability and environmental characteristics. The Dimorphos average temperature of 0.0 K (-273.1 °C) (-459.7°F) provides the baseline for understanding its climate. These extremely cold temperatures make Dimorphos 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), Dimorphos presents a dramatically different thermal environment. Being closer to the Sun than Earth, Dimorphos receives more intense solar radiation, contributing to its temperature profile.

The Dimorphos escape velocity and shape characteristics reveal important details about its gravitational field and rotational dynamics. The Dimorphos 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 Dimorphos to retain a substantial atmosphere. The Dimorphos 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.
