Daphnis Semi-Major Axis

Orbital Radius of Daphnis

The Daphnis semi-major axis is a critical orbital parameter that defines the average distance from the Sun. The Daphnis semi-major axis measures 0.00 AU (approximately 136,500 km), which represents the average orbital radius of Daphnis. This measurement is fundamental to understanding Daphnis's position in the Solar System and its relationship with other celestial bodies.

The orbital radius of Daphnis determines how much solar radiation the planet receives, which directly influences its temperature, climate, and overall environmental conditions. This distance places Daphnis in a specific region of the Solar System, each with unique characteristics and scientific significance.

When we examine the Daphnis semi-major axis 0.00 AU, we gain insights into the planet's orbital mechanics, including its orbital period, velocity, and the gravitational forces at play. This parameter is essential for space mission planning and understanding the dynamics of our Solar System.

Daphnis Mass

Mass of Daphnis in kg

The Daphnis mass is a fundamental property that determines many of the planet's physical characteristics. The mass of Daphnis in kg is approximately 1.00e+14 kg, which is 59720000000.00× less than Earth's mass. This substantial mass creates a significant gravitational field that influences everything from atmospheric retention to orbital dynamics.

Understanding the Daphnis mass allows scientists to calculate other critical properties such as surface gravity, escape velocity, and the planet's ability to retain an atmosphere. The mass also plays a crucial role in determining how Daphnis interacts with other celestial bodies through gravitational forces.

The precise measurement of the mass of Daphnis in kg is essential for space exploration missions, as it affects spacecraft trajectories, landing procedures, and the design of scientific instruments. This fundamental property helps us understandDaphnis's formation history and its place in the evolution of our Solar System.

Daphnis Orbital Period

How Long is a Year on Daphnis?

The Daphnis orbital period defines the length of one complete revolution around the Sun. The Daphnis orbital period is 0.00 hours, which is 53128197.81× shorter than Earth's year. This orbital period determines the length of Daphnis's year and directly influences seasonal patterns, climate cycles, and temperature variations.

The Daphnis orbital period is directly related to its distance from the Sun, following Kepler's laws of planetary motion. Planets farther from the Sun have longer orbital periods, while those closer complete their orbits more quickly. This relationship helps explain why Daphnis takes the time it does to complete one full orbit.

Understanding the Daphnis orbital period is crucial for space mission planning, as it affects launch windows, travel times, and the timing of scientific observations. This fundamental orbital parameter also provides insights into the planet's formation history and its current position in the Solar System's dynamic structure.

How Far is Daphnis from Earth?

Distance Between Daphnis and Earth

How far is Daphnis from Earth? This is a question that fascinates both astronomers and space enthusiasts. The distance between Daphnis and Earth varies throughout their orbital cycles, but on average, Daphnis is approximately 1.49e+8 km(0.999 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 Daphnis 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 Daphnis.

The distance between Daphnis and Earth is not constant due to the elliptical nature of both planets' orbits. When Daphnis 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.

Overview of Daphnis

Daphnis is a fascinating moon in our Solar System that has captured the attention of astronomers and space enthusiasts alike. With a Daphnis radius of 3.8 km, making it 1676.6× 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 136,500 km (0.001 AU) from the Sun, Daphnis occupies a significant place in the Solar System's architecture. As a moon, Daphnis demonstrates the incredible diversity of natural satellites that orbit larger celestial bodies throughout our Solar System.

Physical Characteristics

The Daphnis physical characteristics reveal a world of remarkable dimensions and properties. The Daphnis radius measures 3.8 km, making it 1676.6× smaller than Earth's size. The Daphnis mass of 1.00e+14 kg represents 59720000000.0× smaller than Earth's mass, giving this world substantial gravitational influence.

Orbital Properties

The Daphnis orbit reveals fascinating details about its journey around the Sun and its relationship to other Solar System objects. The Daphnis orbit has a semimajor axis of 136,500 km (0.001 AU), placing it 1096.0× smaller than Earth's distance from the Sun. The Daphnis orbit is nearly circular with an eccentricity of 0, resulting in relatively stable solar heating throughout its year. The Daphnis orbit takes 0.00 hours to complete (53128197.8× smaller than Earth's orbital period), defining the length of its year. The orbital inclination of indicates how much the Daphnis orbit is tilted relative to the Solar System's ecliptic plane. This low inclination means Daphnis follows a path very close to the plane where most planets orbit, suggesting a stable formation history.

Rotation and Tilt

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

Escape Velocity & Flattening

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