Overview of Polydeuces
Polydeuces is a fascinating moon in our Solar System that has captured the attention of astronomers and space enthusiasts alike. With a Polydeuces 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 377,390 km (0.003 AU) from the Sun, Polydeuces occupies a significant place in the Solar System's architecture. As a moon, Polydeuces demonstrates the incredible diversity of natural satellites that orbit larger celestial bodies throughout our Solar System.
Physical Characteristics
The Polydeuces physical characteristics reveal a world of remarkable dimensions and properties. The Polydeuces radius measures 2 km, making it 3185.5× smaller than Earth's size. The Polydeuces mass of 1.00e+13 kg represents 597200000000.0× smaller than Earth's mass, giving this world substantial gravitational influence.
Orbital Properties
The Polydeuces orbit reveals fascinating details about its journey around the Sun and its relationship to other Solar System objects. The Polydeuces orbit has a semimajor axis of 377,390 km (0.003 AU), placing it 396.4× smaller than Earth's distance from the Sun. The Polydeuces orbit is nearly circular with an eccentricity of 0.018 (1.1× Earth's orbital eccentricity), resulting in relatively stable solar heating throughout its year. The Polydeuces orbit takes 0.00 hours to complete (11530197.1× smaller than Earth's orbital period), defining the length of its year. The orbital inclination of 0.171° indicates how much the Polydeuces orbit is tilted relative to the Solar System's ecliptic plane. This low inclination means Polydeuces follows a path very close to the plane where most planets orbit, suggesting a stable formation history.
Rotation and Tilt
The Polydeuces rotation and axial orientation provide crucial insights into its daily and seasonal cycles, as well as its orbital dynamics. The Polydeuces axial tilt of 0° determines the intensity and nature of seasonal variations. With minimal axial tilt, Polydeuces experiences virtually no seasonal changes, maintaining relatively constant temperatures throughout its year. The orbital orientation parameters reveal additional details about Polydeuces'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.
Temperature and Atmosphere
The Polydeuces temperature and atmospheric conditions are fundamental to understanding its habitability and environmental characteristics. The Polydeuces average temperature of 0.0 K (-273.1 °C) (-459.7°F) provides the baseline for understanding its climate. These extremely cold temperatures make Polydeuces 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), Polydeuces presents a dramatically different thermal environment. Being closer to the Sun than Earth, Polydeuces receives more intense solar radiation, contributing to its temperature profile.
Escape Velocity & Flattening
The Polydeuces escape velocity and shape characteristics reveal important details about its gravitational field and rotational dynamics. The Polydeuces 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 Polydeuces to retain a substantial atmosphere. The Polydeuces 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.
FAQs About Polydeuces
How big is Polydeuces compared to Earth?
Polydeuces has a radius of 2 km, making it 3185.5× smaller than Earth's size. In terms of volume, Polydeuces is 0.0× the size of Earth. This size difference significantly impacts the planet's gravity, atmospheric retention, geological processes, and overall planetary characteristics.
How far is Polydeuces from the Sun?
Polydeuces orbits at an average distance of 377,390 km (0.003 AU) from the Sun, placing it 396.4× smaller than Earth's distance from the Sun. This distance determines the amount of solar radiation the planet receives and significantly influences its temperature and climate.
How long is a year on Polydeuces?
A year on Polydeuces lasts 0.00 hours (11530197.1× smaller than Earth's orbital period). This orbital period defines the length of the planet's year and affects seasonal patterns, temperature variations, and the overall climate cycle.
What is Polydeuces made of?
Polydeuces has a density of 1 g/cm³ (5.5× smaller than Earth's density). This density provides important clues about the planet's internal composition. The low density indicates a composition dominated by lighter elements, characteristic of gas giants or icy bodies.
Does Polydeuces have seasons?
Polydeuces has an axial tilt of 0°. With minimal axial tilt, the planet experiences virtually no seasonal changes, maintaining relatively constant temperatures throughout its year.
