At the moment it is about 5 degrees. It is slowly decreasing. Don't worry though, it will take thousands of years to change much.

What is Io's axial tilt?

Io, one of Jupiter's moons, has a very small axial tilt of only about 0.04 degrees. This means that Io's rotational axis is almost perpendicular to its orbital plane, resulting in very minimal changes in the orientation of its poles relative to its orbit around Jupiter.


Why solar eclipse does not occur every time the moon revolves around earth?

The Earth orbits the Sun in a plane that we call the "ecliptic". If the Moon orbited the Earth in that same plane, we would experience eclipses every month. But the plane of the Moon's orbit is about 5 degrees tilted from the ecliptic, and so we only see eclipses at the "nodes" when the Moon's orbital plane crosses the ecliptic at the new or full moons.


Why does a lunar or solar eclipse happen only twice per year?

For an eclipse, Sun, Earth and Moon must be aligned. Most of the time, the Moon doesn't pass exactly in front of the Earth (for a solar eclipse) or behind it (for a lunar eclipse), but passes more to the north or more to the south. This is because the Moon's orbit around the Earth is not exactly in the same plane as Earth's orbit around the Sun.


Why are full moons so common while lunar eclipses are relatively rare Describe or draw the relative positions of the earth the sun and the moon?

Because at most full moons the Moon passes above or below the Sun and not actually right in front of it. That's because the Moon has a tilted orbit. I can't draw a diagram on here so you'll have to do your own homework :)


What is the result of the moons period of rotation?

how is the crater density used in the relative dating

How is the moons orbit positioned relative to the eclptic?

The Moon's orbit is inclined by just over 5 degrees to ecliptic plane.


Why don't you have a lunar eclipse during every full moon?

The moon orbits the Earth and it is tilted by five degrees to the Earth's ecliptic plane, so that the moon will either be above or below the ecliptic at most full moons, this in turn prevents the moon from entering the Earth's shadow - hence no lunar eclipse.


Is the moons orbit in the same 3d plane as earths orbit?

No. For one thing, a plane is, by definition, 2-dimensional. The moon's orbit is tilted about 5 degrees relative to Earth's orbit.


Is the moons orbit around earth straight with respect to earth's orbit around the sun?

No. The moon's orbit is tilted by about 5 degrees relative to Earth's orbit around the sun. This is why we do not see eclipses every month.


Why don't eclipse occur during every full-moon or new moon phase?

It is because the moon's orbit is tilted with respect to the ecliptic by about five degrees, meaning that at most new or full moons, the moon passes above or below the Earth's shadow, preventing an eclipse.

Why doesn't lunar eclipse occur every month?

The plane of the Earth's orbit around the Sun is called the "ecliptic". Most of the other planets and moons orbit in planes that are close to the ecliptic, but none of them have orbital planes that are exactly the same. The Moon's orbital plane is about 8 degrees angled to the ecliptic. So most times, the Moon is either above the ecliptic at the new or full, or below it. It is only when the new moon is on the eclliptic that we have a solar eclipse, and only when the full moon is on the ecliptic that we have a lunar eclipse.

Why do all the planets and most of the moons revolve counterclockwise?

That's how it's tilted on the axis .
