Mneme

Mneme is a fascinating moon in our Solar System that has captured the attention of astronomers and space enthusiasts alike. With a Mneme radius of 2 km, making it 3185.5× smaller than Earth's size, this celestial body presents unique characteristics that distinguish it from other objects in our cosmic neighborhood. Positioned at an average distance of 2.11e+7 km (0.141 AU) from the Sun, Mneme occupies a significant place in the Solar System's architecture. As a moon, Mneme demonstrates the incredible diversity of natural satellites that orbit larger celestial bodies throughout our Solar System.

The Mneme physical characteristics reveal a world of remarkable dimensions and properties. The Mneme radius measures 2 km, making it 3185.5× smaller than Earth's size. The Mneme mass of 1.50e+13 kg represents 398133333333.3× smaller than Earth's mass, giving this world substantial gravitational influence.

The Mneme orbit reveals fascinating details about its journey around the Sun and its relationship to other Solar System objects. The Mneme orbit has a semimajor axis of 2.11e+7 km (0.141 AU), placing it 7.1× smaller than Earth's distance from the Sun. The Mneme orbit is moderately elliptical with an eccentricity of 0.227 (13.6× Earth's orbital eccentricity), creating noticeable seasonal variations in solar radiation. The Mneme orbit takes 0.17 hours to complete (50900.2× smaller than Earth's orbital period), defining the length of its year. The orbital inclination of 148.6° indicates how much the Mneme orbit is tilted relative to the Solar System's ecliptic plane. This high inclination suggests Mneme may have experienced significant gravitational perturbations or formed in a different region of the Solar System.

The Mneme rotation and axial orientation provide crucial insights into its daily and seasonal cycles, as well as its orbital dynamics. The Mneme axial tilt of 0° determines the intensity and nature of seasonal variations. With minimal axial tilt, Mneme experiences virtually no seasonal changes, maintaining relatively constant temperatures throughout its year. The orbital orientation parameters reveal additional details about Mneme'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 Mneme temperature and atmospheric conditions are fundamental to understanding its habitability and environmental characteristics. The Mneme average temperature of 0.0 K (-273.1 °C) (-459.7°F) provides the baseline for understanding its climate. These extremely cold temperatures make Mneme 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), Mneme presents a dramatically different thermal environment. Being closer to the Sun than Earth, Mneme receives more intense solar radiation, contributing to its temperature profile. The elliptical orbit creates significant temperature variations throughout the year, with extreme seasonal changes.

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