As we know that Kepler's laws of planetary motion state that aerial velocity of a planet remains constant

i.e dA/dt = constant , Where A is the area swept by the planet around sun. so to maintain the aerial velocity constant,planet has variable velocity.

Why is 12000 lunar orbits the speed of light?

The speed of light is approximately 299,792 kilometers per second. The number of lunar orbits required to cover this distance would be 12000 because the circumference of the Moon's orbit around the Earth is about 10,000 kilometers. Multiplying this by 12000 gives an approximate value close to the speed of light.


What speed does the hubble telescope travel?

The Hubble Space Telescope orbits Earth at a speed of about 17,000 miles per hour (27,000 km/h). At this speed, it completes an orbit around Earth approximately every 97 minutes.


How long would it take for space travelers to get to Jupiter from Earth if the average speed of the spacecraft is 55000 mph?

It would take approximately 13 months to reach Jupiter if the spacecraft maintains an average speed of 55,000 mph. This estimate is based on the average distance between Earth and Jupiter when they are at their closest points in their orbits.


What is sun-earth-moon system?

Like our solar system, the other planets and their moons,are systems in their own right. The Earth-Moon system means that both bodies interact with each other, gravitationally. The moon affects our tides, our axial tilt and our rotational speed. Earth affects the Moon in rotational speed, orbital characteristics, and axial tilt.


When a satellite orbits around the earth at constant speed it does what?

The earth's orbit around the sun is elliptical, so the earth moves at a constantly varying velocity as it moves closer to the sun (perihelion) or further away (aphelion). The earth's angular velocity (speed of movement) is considerably greater at perihelion than it is at aphelion. So in that sense, the earth orbits at a constantly varying speed. But there is a sense in which the earth orbits at constant speed. Similar segments of the elliptical orbit are crossed in similar lengths of time wherever the earth is in its orbital path. The earth gets through 10% of its path in the same length of time whether it is at aphelion (moving slowly) or perihelion (moving fast). The absolute speed at which the earth moves varies, but the rate at which it orbits is constant. ---- The realisation that the earth's orbit was both speed variant (absolute speed of motion) and speed constant (segment of elliptical orbit covered) was the crucial breakthrough that allowed Johannes Kepler to solve the longstanding problem of the regression of Mercury (why Mercury appears to go backward in its orbit some of the time). Discovering that the earth's orbit is elliptical (astronomers had always assumed orbits were based on perfect circles) was how Kepler showed finally that the earth goes around the sun (and not the other way around).

Does a space station go fast or slow?

A space station orbits the Earth at a high speed, typically around 28,000 kilometers per hour (17,500 miles per hour). This speed allows it to counteract the pull of gravity and remain in orbit around the Earth.
