How Far is 10370 Hylonome from Earth?

Distance Between 10370 Hylonome and Earth

How far is 10370 Hylonome from Earth? This is a question that fascinates both astronomers and space enthusiasts. The distance between 10370 Hylonome and Earth varies throughout their orbital cycles, but on average, 10370 Hylonome is approximately 3.63e+9 km(24.261 AU) away from Earth. This distance changes as both planets orbit the Sun, with the closest approach (opposition) and farthest separation (conjunction) creating significant variations.

The question "How far is 10370 Hylonome from Earth?" has practical implications for space exploration. This distance determines travel time for spacecraft, communication delays for mission control, and the amount of fuel required for interplanetary missions. Understanding this distance is essential for planning future missions to 10370 Hylonome.

The distance between 10370 Hylonome and Earth is not constant due to the elliptical nature of both planets' orbits. When 10370 Hylonome and Earth are on the same side of the Sun (opposition), they are at their closest, making this the optimal time for observations and potential missions. Conversely, when they are on opposite sides of the Sun (conjunction), they are at their farthest separation, which can exceed the average distance significantly.

Physical Characteristics

The 10370 Hylonome physical characteristics reveal a world of remarkable dimensions and properties. The 10370 Hylonome radius measures 70 km, making it 91.0× smaller than Earth's size.

Orbital Properties

The 10370 Hylonome orbit reveals fascinating details about its journey around the Sun and its relationship to other Solar System objects. The 10370 Hylonome orbit has a semimajor axis of 3.78e+9 km (25.261 AU), placing it 25.3× Earth's distance from the Sun. At its closest approach (perihelion), 10370 Hylonome comes within 2.83e+9 km of the Sun, while at its farthest point (aphelion), it reaches 4.73e+9 km, creating a 50.1% variation in solar distance. The 10370 Hylonome orbit is moderately elliptical with an eccentricity of 0.25 (15.0× Earth's orbital eccentricity), creating noticeable seasonal variations in solar radiation. The 10370 Hylonome orbit takes 12.38 hours to complete (708.2× smaller than Earth's orbital period), defining the length of its year. The orbital inclination of 4.141° indicates how much the 10370 Hylonome orbit is tilted relative to the Solar System's ecliptic plane. This low inclination means 10370 Hylonome follows a path very close to the plane where most planets orbit, suggesting a stable formation history.

Rotation and Tilt

The 10370 Hylonome rotation and axial orientation provide crucial insights into its daily and seasonal cycles, as well as its orbital dynamics. The 10370 Hylonome axial tilt of 0° determines the intensity and nature of seasonal variations. With minimal axial tilt, 10370 Hylonome experiences virtually no seasonal changes, maintaining relatively constant temperatures throughout its year. The orbital orientation parameters reveal additional details about 10370 Hylonome's position in space. The mean anomaly of indicates the planet's current position in its orbit relative to its perihelion. The argument of periapsis of shows how the orbit's orientation changes over time due to gravitational perturbations. The longitude of ascending node of defines the reference point where the orbit crosses the ecliptic plane.

Temperature and Atmosphere

The 10370 Hylonome temperature and atmospheric conditions are fundamental to understanding its habitability and environmental characteristics. The 10370 Hylonome average temperature of 0.0 K (-273.1 °C) (-459.7°F) provides the baseline for understanding its climate. These extremely cold temperatures make 10370 Hylonome 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), 10370 Hylonome presents a dramatically different thermal environment. Being farther from the Sun than Earth, 10370 Hylonome receives less solar radiation, resulting in cooler conditions. The elliptical orbit creates significant temperature variations throughout the year, with extreme seasonal changes.

Escape Velocity & Flattening

The 10370 Hylonome escape velocity and shape characteristics reveal important details about its gravitational field and rotational dynamics. The 10370 Hylonome 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 10370 Hylonome to retain a substantial atmosphere. The 10370 Hylonome 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.
