This is almost certainly due to the fact that a full rotation of the Earth is shorter than a day. As the Earth moves around the sun, it has to turn slightly further than a full rotation to bring the sun back to the same position in the sky. Additionally, Earth's position relative to Jupiter will have changed slightly.
- dabluecaboose 4y agoOff the top of my head I'd have to say the planetary ephemerides are more of a factor than the earth's rotation. That much we have pretty down pat, otherwise they'd just announce it's at (Day+23.6h)
