Stephano
Alternative name: Also known as: S/1999 U 2
Radius of Stephano
The radius of Stephano is one of its most fundamental physical characteristics. The Stephano radius measures approximately 16 km, making it 398.19× smaller than Earth. This measurement represents the average distance from the center of Stephano to its surface, providing crucial information about the celestial body's size and volume.
Understanding the Stephano radius is essential for calculating other important properties such as surface area, volume, and gravitational characteristics. The radius directly influences how we perceive and study this fascinating object in our Solar System.
Orbital Radius of Stephano
The Stephano semi-major axis is a critical orbital parameter that defines the average distance from the Sun. The Stephano semi-major axis measures 0.05 AU (approximately 8.00e+6 km), which represents the average orbital radius of Stephano. This measurement is fundamental to understanding Stephano's position in the Solar System and its relationship with other celestial bodies.
The orbital radius of Stephano determines how much solar radiation the planet receives, which directly influences its temperature, climate, and overall environmental conditions. This distance places Stephano in a specific region of the Solar System, each with unique characteristics and scientific significance.
When we examine the Stephano semi-major axis 0.05 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.
Mass of Stephano in kg
The Stephano mass is a fundamental property that determines many of the planet's physical characteristics. The mass of Stephano in kg is approximately 2.20e+16 kg, which is 271454545.45× less than Earth's mass. This substantial mass creates a significant gravitational field that influences everything from atmospheric retention to orbital dynamics.
Understanding the Stephano 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 Stephano interacts with other celestial bodies through gravitational forces.
The precise measurement of the mass of Stephano 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 understandStephano's formation history and its place in the evolution of our Solar System.
How Long is a Year on Stephano?
The Stephano orbital period defines the length of one complete revolution around the Sun. The Stephano orbital period is -0.19 hours, which is -46649.15× shorter than Earth's year. This orbital period determines the length of Stephano's year and directly influences seasonal patterns, climate cycles, and temperature variations.
The Stephano 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 Stephano takes the time it does to complete one full orbit.
Understanding the Stephano 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.
Distance Between Stephano and Earth
How far is Stephano from Earth? This is a question that fascinates both astronomers and space enthusiasts. The distance between Stephano and Earth varies throughout their orbital cycles, but on average, Stephano is approximately 1.42e+8 km(0.946 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 Stephano 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 Stephano.
The distance between Stephano and Earth is not constant due to the elliptical nature of both planets' orbits. When Stephano 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.
