SUMMARY

The discussion centers on the impact of halving Earth's orbital period around the sun on the duration of solar and sidereal days. It is established that a solar day is approximately 4 minutes longer than a sidereal day due to the Earth's rotation and its movement around the sun. If Earth's orbital speed doubles, the sun would appear to move twice as far across the sky, necessitating an additional 8 minutes to catch up, resulting in a solar day of approximately 24 minutes and 4 seconds. This conclusion confirms that the relationship between orbital speed and solar day length is directly proportional.

PREREQUISITES
  • Understanding of solar and sidereal days
  • Basic knowledge of Earth's rotation and orbital mechanics
  • Familiarity with astronomical terminology
  • Concept of angular displacement in celestial motion
NEXT STEPS
  • Research the effects of orbital mechanics on time measurement

I know that a solar day is about 4 minutes longer than a sidereal day.

But what if the Earth orbital period around the sun is halved, but the rotation period is same?

Will the solar day still be about 4 minutes longer?

Thanks.

The 4minutes is to account for the distance across the sky the sun moves in a day.
So it takes 23:56 min for the Earth to rotate but then you have to move another 4mins to catch up with the sun which has moved on a bit.
If the earht moved twice as fast around the sun, the sun would have moved twice as far and so you would need (roughly) an extra 8 minutes to catch up and a solar day would 24:04.

this makes sense, thanks.
