Moon Wobble

🔹 Recently, the National Aeronautics and Space Administration (NASA) has highlighted Moon’s Wobble as a potential problem in the near future.

🔹 About

1. When the Moon makes its elliptical orbit, its velocity varies and alters causing our perspective of the "light side" to appear at slightly different angles.

2. It is a cyclical shift in the moon’s orbit, it is a regular swaying (Oscillation) in the moon’s orbit.

3. It was first documented in 1728. 

4. This wobble takes over an 18.6-year period to complete.

🔹 Impacts

1. It impacts the gravitational pull of the moon, and therefore, indirectly influences the ebb and flow of tides on the Earth.

2. Each wobble cycle has the power to amplify and suppress the tides on Earth.

🔹 Tides

1. These are the alternate rise and fall of the ocean water. 

2. It is caused by the combined effects of the gravitational force exerted on Earth by the Sun, the gravitational force exerted on Earth by the Moon and rotation of the Earth.
