Is the Earths rotational axis tilted 23.5 degrees to the plane of orbital rotation around the Sun?

Answer 1

Earth is tilted at 23.5 degrees. it is thought to be of an impact by a moon size object billions of years ago.

============================

Another take on the same question:

The Earth's axis is not parallel to anything else. The angle of 'tilt' depends on what

you're comparing it to. If you compare it to the perpendicular to the plane of Earth's

orbit, then the angle is about 23.5 degrees. It doesn't require an explanation, since

no planet has an axis that's perpendicular to the plane of its orbit, there's no reason

why it should, and the angle of 'tilt' is different for each planet.

Answer 2

Yes, that is correct. The Earth's rotational axis is tilted at an angle of 23.5 degrees relative to its orbital plane around the Sun. This tilt is what causes the changing seasons on Earth as different parts of the planet receive varying amounts of sunlight throughout the year.

Answer 3

Yes well almost, to be more precise. The answer is no. It's an easy mistake to make when you are busy. I've done it myself. The Earth's axis is tilted about 23.5 degrees to the normal (perpendicular) to the plane of the orbit, of course.

If you define the angle between a line (the Earths axis in this case) and a plane (the plane of the Earths orbit around the Sun) as the least possible angle between the line and any line in the plane then the Earths axis is tilted 90° - 23,5° = 66,5°

Answer 4

The Earth is tilted 23.5 degrees from the plane of the ecliptic, or the plane of the Earth's orbit around the Sun.

However, this doesn't mean that the Earth is wobbling around like a top that's about to fall over. The Earth is more like an enormous gyroscope, spinning steadily and always pointing the same way - just a little bit tipped compared to its motion around the Sun.

Answer 5

The tilt can be understood as follows. Imagine the plane in which Earth orbits the Sun. Draw a line perpendicular (at right angles) to this plane. If that is a planet's axis of rotation, that would be zero tilt. Earth's axis of rotation is 23 1/2 degrees tilted with respect to this direction.

Answer 6

Not an answer, another question. I get two answers in regard to the angle of the ecliptic (earth's nearly circular orbit around the sun relative to the sun's equator or equatorial plane). One is 7.25° and 23.4° which is nearly the same angle as earth's axial tilt. Do we experience seasonal changes due to earth's tilt to the plane of the sun's equator or is the earth actually tilted (nonperpendicular) to it's own ecliptic? If that is the case, does the tilt of the ecliptic, the earth moving above and below the sun's equator, play no effect on the earth's climate?

Answer 7

That's logical, but not the case for Earth. Instead, Earth has seasons because our planet's axis of rotation is tilted at an angle of 23.5 degrees relative to our orbital plane – the plane of Earth's orbit around the sun. The tilt in the axis of the Earth is called its obliquity by scientists.

Answer 8

No. It varies between 22.1° and 24.5°, with a 41,000-year period.

Answer 9

The ecliptic is the plane of the Earth's orbit around the sun.

The Earth's axis (of rotation) is NOT perpendicular to that plane,

its tilted at 23.44 degrees.
