And, together with its thickness, Kerbin's atmosphere is ideally suited for aircraft flight.Ī synchronous orbit is achieved with a semi-major axis of 3 463.33 km. Parachutes perform well in Kerbin's dense air, allowing landings on both land and water to be accomplished without the aid of propulsion.īecause of the presence of oxygen, jet engines can operate in Kerbin's atmosphere. For most conditions, a periapsis altitude of about 30 km should result in an aerocapture. The periapsis altitude required for a successful aerocapture depends on the spacecraft's drag characteristics, its approach velocity, and the desired apoapsis of the resulting orbit. The thickness of Kerbin's atmosphere makes it well suited for aerobraking from a high-speed interplanetary intercept. The base temperature is the temperature less latitudinal and diurnal adjustments it is roughly equal to the global mean temperature. The velocity required to escape a body from a given altitude is always exactly the square root of two times the velocity of a circular orbit around the body at that height: ( 2 ∗ v ). Many interplanetary missions expend over half of their Δv in reaching Kerbin orbit. The only rocky planet that requires a higher Δv to attain orbit is Eve. With the introduction of version 1.0.3, attaining low Kerbin orbit requires a Δv of approximately 3400 m/s (vacuum), though the exact amount depends on the efficiency of the ascent profile and the aerodynamics of the launch vehicle and payload. Reaching a stable orbit around Kerbin is one of the first milestones a player might achieve in the game. However, Tylo has only 80% of Kerbin's mass. Jool's moon Tylo has the same radius of Kerbin, though it may be classified as larger, as the highest point on Tylo is about 5 km higher than the highest point on Kerbin. It is the third largest celestial body that orbits Kerbol, following Jool and Eve. Kerbin is the third planet in orbit around the star Kerbol. It is also the Earth analog for the game but, unlike Earth, it has two moons instead of one. Kerbin is the home planet of the Kerbals, the location of the Space Center and other facilities, and the main focus of Kerbal Space Program. ↑ 1.0 1.1 1.2 1.3 The distances are given from the body's center, not from the surface (unlike ingame).
