no the earth is bigger than the moon
the shape
No - the moon itself stays the same shape. The phases of the moon change as the earth and moon orbit round the sun. The phases are simply the amount of sunlight reflected in relation to the position of the earth's shadow cast on the moon
The shape of the moon's orbit around the Earth is an ellipse.
The moon's shape remains the same at all times. The aspect of the moon changes because the shadow moves across its surface as it revolves around the earth.
Technically, the shape of the moon never changes. What changes is what we saw on Earth. The shape we see depends on the alignment of the Moon, Earth, and Sun.
No. Everybody anywhere on earth who can see the moon at all sees the same illuminated shape at the same time.
It will be a waning gibbous. The moon itself will remain the same shape it always has; spherical. However, from the Earth, it will resemble an oval-like shape; almost a half circle.
Every month as the Moon cycles through its phases it appears to change shape. The Moon always has the same spherical shape, but stargazers on Earth see different fractions of the dark and illuminated portions of the Moon as the Moon orbits Earth. The common urban myth that Earth's shadow falling on the Mooncauses lunar phases is incorrect.
a ball
The moon orbits the earth almost a complete circle.
The sun is approximately 400 times the size of the moon, however, it is also approximately 400 times farther away. This relationship cancels out and makes the sun and the moon appear observationally to be the same size on earth.
The moon supposedly "changes shape" all the time, as the moon is constantly orbiting the Earth however the moon doesn't actually change shape, it is the amount of the sunlit side of the Earth that we see changing.
