Sun

Radius of Sun

The radius of Sun is one of its most fundamental physical characteristics. The Sun radius measures approximately 695,508 km, making it 109.17× larger than Earth. This measurement represents the average distance from the center of Sun to its surface, providing crucial information about the celestial body's size and volume.

Understanding the Sun 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.

Mass of Sun in kg

The Sun mass is a fundamental property that determines many of the planet's physical characteristics. The mass of Sun in kg is approximately 1.99e+30 kg, which is 333054.25× greater than Earth's mass. This substantial mass creates a significant gravitational field that influences everything from atmospheric retention to orbital dynamics.

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

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