perihelion
In a two-planet system, when one planet is closest to its star and moving fastest (maximized velocity), the other planet is farthest away and moving slowest. This can affect the period of the two planets in their orbits, potentially leading to variations in their orbital time intervals.
The velocity a rocket must reach to establish an orbit around the Earth is called orbital velocity. It is the speed required for an object to overcome gravitational pull and maintain a stable orbit around the planet. The orbital velocity depends on the altitude of the orbit and follows Kepler's laws of planetary motion.
Doubling the mass of a satellite would result in no change in its orbital velocity. This is because the orbital velocity of a satellite only depends on the mass of the planet it is orbiting and the radius of its orbit, but not on the satellite's own mass.
It is the orbital velocity (speed and direction) or orbital speed (rate of motion). It is usually stated as "average orbital speed" but is actually "mean orbital speed."
Mercury is the fastest orbiting planet in the inner Solar System, with an average orbital velocity of 47.87 km/s.
Pluto is the planet that has the lowest orbital velocity relative to that of the earth. The orbital velocity of Pluto is 0.159.

Orbital velocity refers to the speed at which a planet travels in its orbit.
Mercury has the fastest orbital velocity, at about 49 thousand kilometers per second.Mercury: 48.651Venus: 34.874Earth: 29.663Mars: 24.025Jupiter: 13.012Saturn: 9.604Uranus: 6.749Neptune: 5.410These number are based on major-axis, and on an assumed circular orbit, so they will not agree with the official stated mean orbital velocity.
In a two-planet system, when one planet is closest to its star and moving fastest (maximized velocity), the other planet is farthest away and moving slowest. This can affect the period of the two planets in their orbits, potentially leading to variations in their orbital time intervals.
Mercury has an average orbital velocity of about 47.87 km/s (29.73 mi/s) as it travels around the Sun. It is the fastest planet in our solar system due to its close proximity to the Sun and strong gravitational pull.
Jupiter has an orbital velocity of 13.1km/s.
As the planet approaches perihelion (point of nearest approach to the Sun), its orbital velocity gets faster, and it is fastest at perihelion. Similarly, at aphelion (point of furthest approach to the Sun), the orbital velocity is slowest.
