Discover Earth's Orbital Velocities at Perihelion and Aphelion

In summary, Earth's orbital velocity is the speed at which it revolves around the Sun, which is approximately 107,000 kilometers per hour or 67,000 miles per hour. This velocity is affected by the mass of the Sun, the distance between Earth and the Sun, and the gravitational force between the two bodies. However, it does not directly impact the seasons, as the tilt of Earth's axis is what causes the changes. Earth's orbital velocity is not constant and varies slightly throughout the year due to changes in Earth's distance from the Sun and the gravitational pull of other planets. It can be measured using instruments such as radar or by calculating the distance traveled in a specific time period, as well as by using Kepler's laws of

The orbital velocities of Earth at its perihelion and aphelion can be found through various sources, including scientific databases, educational websites, and astronomical charts. Some reputable sources for this information include NASA's Jet Propulsion Laboratory, the National Oceanic and Atmospheric Administration, and the Royal Astronomical Society. Additionally, many astronomy textbooks and online resources also provide this data. It is important to note that the orbital velocities at perihelion and aphelion may vary slightly due to factors such as the Earth's changing distance from the Sun and gravitational influences from other celestial bodies.
