Distance Between 47171 Lempo and Earth

How far is 47171 Lempo from Earth? This is a question that fascinates both astronomers and space enthusiasts. The distance between 47171 Lempo and Earth varies throughout their orbital cycles, but on average, 47171 Lempo is approximately 5.73e+9 km(38.332 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 47171 Lempo 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 47171 Lempo.

The distance between 47171 Lempo and Earth is not constant due to the elliptical nature of both planets' orbits. When 47171 Lempo 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 47171 Lempo physical characteristics reveal a world of remarkable dimensions and properties. The 47171 Lempo radius measures 197 km, making it 32.3× smaller than Earth's size.

Orbital Properties

The 47171 Lempo orbit reveals fascinating details about its journey around the Sun and its relationship to other Solar System objects. The 47171 Lempo orbit has a semimajor axis of 5.88e+9 km (39.332 AU), placing it 39.3× Earth's distance from the Sun. At its closest approach (perihelion), 47171 Lempo comes within 4.58e+9 km of the Sun, while at its farthest point (aphelion), it reaches 7.19e+9 km, creating a 44.3% variation in solar distance. The 47171 Lempo orbit is moderately elliptical with an eccentricity of 0.221 (13.2× Earth's orbital eccentricity), creating noticeable seasonal variations in solar radiation. The 47171 Lempo orbit takes 1.06 days to complete (344.2× smaller than Earth's orbital period), defining the length of its year. The orbital inclination of 8.4° indicates how much the 47171 Lempo 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.

Rotation and Tilt

The 47171 Lempo rotation and axial orientation provide crucial insights into its daily and seasonal cycles, as well as its orbital dynamics. The 47171 Lempo axial tilt of 0° determines the intensity and nature of seasonal variations. With minimal axial tilt, 47171 Lempo experiences virtually no seasonal changes, maintaining relatively constant temperatures throughout its year. The orbital orientation parameters reveal additional details about 47171 Lempo'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 47171 Lempo temperature and atmospheric conditions are fundamental to understanding its habitability and environmental characteristics. The 47171 Lempo average temperature of 0.0 K (-273.1 °C) (-459.7°F) provides the baseline for understanding its climate. These extremely cold temperatures make 47171 Lempo 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), 47171 Lempo presents a dramatically different thermal environment. Being farther from the Sun than Earth, 47171 Lempo receives less solar radiation, resulting in cooler conditions. The elliptical orbit creates significant temperature variations throughout the year, with extreme seasonal changes.

The 47171 Lempo escape velocity and shape characteristics reveal important details about its gravitational field and rotational dynamics. The 47171 Lempo 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 47171 Lempo to retain a substantial atmosphere. The 47171 Lempo 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.
