The best source for finding the actual velocity and position of Earth at a specific time is from official scientific databases, such as NASA's Jet Propulsion Laboratory (JPL) or the International Earth Rotation and Reference Systems Service (IERS). These organizations have highly accurate and regularly updated data on Earth's motion.
The velocity and position of Earth are constantly changing due to factors like gravitational forces from other celestial bodies. As a result, the data is continuously updated and can be accessed in real-time through scientific databases.
While it is possible to calculate the velocity and position of Earth using mathematical equations and data from scientific databases, it requires a high level of expertise and access to advanced tools and technology. It is recommended to use the data from official sources mentioned above.
Yes, Earth's velocity and position do vary throughout the year due to its elliptical orbit around the sun. This means that the distance between Earth and the sun, as well as its speed, change depending on the time of year.
Yes, it is possible to find the velocity and position of Earth for any historical time period. Scientific databases, such as JPL and IERS, have data that dates back several decades and can be accessed for research purposes.
