# What is the Earth's axis?

A:

The Earth's axis is positioned at an angle of 23.5 degrees away from the plane of the ecliptic. An objects axis, or axial tilt, also referred to as obliquity, is the angle between an objects orbital axis and rotational axis, or regularly, the angle between its orbital plane and equatorial plane.

The Earth's axis is determined through a number of steps. The first is to locate the line which passes through the sun's north and south equators. The next step is to use the plane of the ecliptic, which is an imaginary disc that surrounds the suns equator in all directions and that is also where all of the planets in the solar system are located. The Earth's axis is determined by measuring its angle in relation to the sun's axis of rotation.

The Earth is constantly spinning on its axis, allowing sunlight to shine on different areas of the Earth at different times of the day, creating daytime when the Sun hits a specific area. When the Sun is not shining on a specific area of the Earth, it is nighttime. Since the Sun does not hit all of the Earth at the same time, it is daytime in some parts of the world, while it is nighttime in others.

According to Universe Today, the duration of a day on Earth is the time it takes for the planet to complete a rotation around its axis. The Earth’s rotation takes 23 hours, 56 minutes and 4.1 seconds.
