Does the earth rotate around the sun at the exact same path every year?

Question

If it doesnt does it have any impact on climate change?

Rite I got that thanks solly, but how do they know its a 40k year cycle or 22deg tilt, how do they know this, it could go to 90deg tilt for all they know. its space they would want to be very percise in there calculations to get that right

Answer 1

For all intents and purposes the earth follows the same path from one year to the next. There are minor changes which over periods of tens of thousands of years cause significant changes in the Earth's climate.

The Earth itself 'wobbles and bounces' in space and it does this in three ways...

PRECESSION (gyroscopic precession)
Changes in the way the earth rotates in much the same way that a gyroscope moves. The gyroscope rotates areound an axis but whilst the bottom of the axis remains in one place the top moves about.

AXIAL TILT (obliquity or axial inclination)
Referes to the inclination of Earth's rotational axis relevant to it's orbital plane. Or to put it another way, the Earth is leaning. Currently it's at an angle of 23 degrees 27 minutes and this varies by a degree or two either way.

ECCENTRICITY (orbital or elliptical eccentricity).
Another type of wobble, perhaps best likened to the way that a badly or loosely fitted wheel would wobble when in motion.

All three impact on climate and collectively this is known as Milankovitch Cycles. Together, and with other factors involved, they do have an effect on our climate but only over long periods of time.

The shortest cycle is 12,000 years but it's not a case of repeating at regular intervals, some of these are irregular cycles. When two or more cycles come together they can have an amplifying effect or a cancelling out effect.

In short, yes the way the earth moves affects climate but over periods typically of 100,000 years and more.

Answer 2

The old professor says: The first thing I have to clear up is the Earth rotates on its axis, but REVOLVES around the sun...two different things altogether. The previous answers are for the most part right, but they are all forgetting one very important thing...the orbit of the earth is NOT an ellipse or circle in the true sense. What? Listen children....the sun is moving through space along with all the other stars and the planets go right along with it! The TRUE shape of the Earth's orbit is an elliptical SPIRAL and looks similar to a stretched Slinky spring as it travels through space along with the sun at its center. Since it is a spiral, it will never go over the same space again. Some effect on climate as the perihelion and aphelion are not in sync with the axial tilt's precession.

Answer 3

No. The earth's axis "wobbles" slightly. This is a 40K year cycle, and it ABSOLUTELY affects climate change.

Answer 4

there is not any consumable potential or a clean tension , required to maintain the planets in action. It exchange right into a momentum utilized to all gaseous platforms [ unfold-ed and thrown aside ] by employing the "super sunlight", spinning with rapid rotation , because of the fact the formation of "photograph voltaic gadget unit " [broken spinning sunlight]. nonetheless the comparable "photograph voltaic gadget unit" is spinning now with "sluggish velocity" with none consumable tension in outer area and the discern physique as unique component of huge sunlight with very sluggish velocity.. later on those gaseous platforms have been cooled and planets have been shaped. there is not any place of interplanetary gravitational charm or repulsion in between photograph voltaic gadget [planets and sunlight or planets and satellites]. The photograph voltaic planets are nonetheless shifting far off from sunlight very slowly as consistent with regulation of increasing universe. The rotation and revolution would not require any exterior tension from sunlight, to maintain them in orbital action. The sunlight ' will die as Little dwarf ineffective megastar" after billions of years , like many stars do, in different galaxies. nonetheless the planets "will save on shifting as they are" , yet with greater beneficial orbits and with sluggish rotations velocity,. there is not any theory for interplanetary orbital factors of interest of heavy cosmic bodies coming closer, while planets do alignments coming closer and closer of their orbits forming a extensive one sided amassing.of planets bunch which incorporates their small products of satellites. .

Answer 5

It does not stay on the exact track every year...ever notice how sometimes we will have a cooler summer or a warmer winter. I read about it in a science book...sorry I can't remember what book though.

Answer 6

nope. not the exact path. the gravitation pull from the other planetary bodies in the system produce orbital wobble as they pull the earth about in its orbit.
