Can you run a cable from Earth to the moon?

Originally Answered: Can we connect Moon and Earth via cable? No, it’s in orbit and so the cable would snap. It would only be possible if the Earth always presented the same face to the moon.

Can we build a tower to the moon?

No. The moon and move at different speeds, so the tower would be pulled apart. And even it was infinitely strong, it would end up pulling the moon down.

Could you build a bridge from the Earth to the moon?

Originally Answered: Could we theoretically build a bridge to the moon? No. The distance to the moon varies from orbit to orbit, as does it’s position in relation to our equator, so the bridge would have to be built of some extremely elastic materiel not yet imagined.

Can we pull the moon closer?

The Moon will swing ever closer to Earth until it reaches a point 11,470 miles (18,470 kilometers) above our planet, a point termed the Roche limit. “Reaching the Roche limit means that the gravity holding it [the Moon] together is weaker than the tidal forces acting to pull it apart,” Willson said.

How long would space elevator take?

Travel on a space elevator would not be fast! The travel time from one end to the other would be several days to a month. To put the distance in perspective, if the climber moved at 300 km/hr (190 mph), it would take five days to reach geosynchronous orbit.

What happens to the Moon when it revolve around the Sun?

As the Moon revolves around Earth, both objects also progress in orbit around the Sun. After completing one revolution with respect to the stars, the Moon must continue a little farther along its orbit to catch up to the same position it started from relative to the Sun and Earth.

Could a space elevator be built on the Moon?

Earth-based space elevators would be too taxing for any existing material — Earth’s stronger gravitational pull and rotation speed would snap the cable before it could be completed. But the risk of a catastrophic collapse, the researchers say, is lower when the cable is only tethered to the Moon.

What is the eccentricity of the Moon’s orbit around Earth?

4.1 Introduction The Moon revolves around Earth in an elliptical orbit with a mean eccentricity of 0.0549. Thus, the Moon’s center-to-center distance from Earth varies with mean values of 363,396 km at perigee to 405,504 km at apogee. The lunar orbital period with respect to the stars (sidereal month) is 27.32166 days (27d 07h 43m 12s).

How does the Earth’s orbit affect the length of the lunation?

With an eccentricity of 0.0167, Earth’s orbit is about one third as elliptical as the Moon’s orbit. Nevertheless, it affects the length of the lunation by producing shorter lunations near aphelion and longer lunations near perihelion.
