Eirene

Radius of Eirene

The radius of Eirene is one of its most fundamental physical characteristics. The Eirene radius measures approximately 2 km, making it 3185.50× smaller than Earth. This measurement represents the average distance from the center of Eirene to its surface, providing crucial information about the celestial body's size and volume.

Understanding the Eirene 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 Eirene

The Eirene semi-major axis is a critical orbital parameter that defines the average distance from the Sun. The Eirene semi-major axis measures 0.16 AU (approximately 2.37e+7 km), which represents the average orbital radius of Eirene. This measurement is fundamental to understanding Eirene's position in the Solar System and its relationship with other celestial bodies.

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

When we examine the Eirene semi-major axis 0.16 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 Eirene in kg

The Eirene mass is a fundamental property that determines many of the planet's physical characteristics. The mass of Eirene in kg is approximately 9.00e+13 kg, which is 66355555555.56× less than Earth's mass. This substantial mass creates a significant gravitational field that influences everything from atmospheric retention to orbital dynamics.

Understanding the Eirene 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 Eirene interacts with other celestial bodies through gravitational forces.

The precise measurement of the mass of Eirene 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 understandEirene's formation history and its place in the evolution of our Solar System.

How Long is a Year on Eirene?

The Eirene orbital period defines the length of one complete revolution around the Sun. The Eirene orbital period is 0.21 hours, which is 41540.28× shorter than Earth's year. This orbital period determines the length of Eirene's year and directly influences seasonal patterns, climate cycles, and temperature variations.

The Eirene 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 Eirene takes the time it does to complete one full orbit.

Understanding the Eirene 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 Eirene and Earth

How far is Eirene from Earth? This is a question that fascinates both astronomers and space enthusiasts. The distance between Eirene and Earth varies throughout their orbital cycles, but on average, Eirene is approximately 1.26e+8 km(0.841 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 Eirene 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 Eirene.

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