# How would the solar and sidereal time differ if the Earth would rotate clockwise?

Contents

Sidereal day is 23 hours, 56 minutes and 4.1 seconds by definition, it is defined so the solar day take 24 hrs. This is 3 minutes 55.9 seconds longer than the sideral day with a counter clockwise rotation. If the rotation were clockwise, the solar day will be shorter by about the same margin (~4 minutes).

## What is the time difference between sidereal day and solar day in the rotation of Earth?

The sidereal day is ~4 minutes shorter than the solar day. The sidereal day is the time it takes for the Earth to complete one rotation about its axis with respect to the ‘fixed’ stars.

## What would happen if the Earth rotates in an opposite direction?

If the earth abruptly changed its rotational direction, probably many things we see every day would be destroyed. Skipping over the transition, however, an earth rotating in the opposite direction would, among other things, cause the sun, moon and stars to appear to rise in the west and set in the east.

## Does the length of the sidereal day depend on the direction that the Earth rotates or the direction that Earth revolves around orbits the sun?

The sidereal day of a planet does not depend on direction, it only depends on the speed of rotation. As it is known that the Earth rotates and revolves in a similar direction, and the difference between the length of the solar day and the sidereal day is 3 minutes and 56 seconds.

## What would happen if the Earth spun slower?

If the Earth gradually slowed, the bulging water from the oceans would begin to move away from the equator towards the poles. Once Earth stopped spinning completely, leaving it as a sphere, the oceans would flood most of Earth leaving one giant megacontinent around the middle of the planet.

## What would happen if Earth had rings?

The rings would probably reflect so much sunlight that the planet would never fully plunge into darkness, but remain in a gentle twilight even in the depth of night. During the day, the rings could potentially cause light levels on Earth to skyrocket [source: Atkinson].

## Why do sidereal and solar days differ in length?

The difference between the sidereal and solar day is due to the orbital motion of the planet. For the planets with their orbital motion in the same direction as their rotation (Mercury, Earth, Mars, Jupiter, Saturn, and Neptune), the solar day is longer than the sidereal day.

## What is the difference between a sidereal year and a tropical year?

Sidereal year is for revolution of the Earth referred to stars. Tropical year is the period between two successive (same) equinox instants.

## What is local sidereal time mean?

Local sidereal time (LST) is the time according to the stars at your longitude. Let’s assume that star X is on the meridian at 0 hours (midnight). The same star will return to the meridian after 23 hours 56 minutes 4 seconds (approximately) of clock time.

## Which would be different if Earth rotated from east to west but at the same rate?

science test

Term Definition
Which property of the Sun most affects the strength of gravitational attraction between Sun and Earth? Mass
Which would be different if Earth rotates from east to west but at the same rate? The direction of the Sun’s apparent motion across the sky

## What planet rotates backwards compared to Earth?

Our neighboring planet Venus is an oddball in many ways. For starters, it spins in the opposite direction from most other planets, including Earth, so that on Venus the sun rises in the west.

## What would happen if the sun exploded?

The good news is that if the Sun were to explode – and it will eventually happen – it wouldn’t happen overnight. … During this process, it will lose its outer layers to the cosmos, leading to the creation of other stars and planets in the same way that the violent burst of the Big Bang created Earth.
