If we use the Doppler method to measure the period with which a star alternately moves toward and away from planet Earth (us) due to an orbiting planet, then we also know the: orbital period of the planet.

The Doppler effect is also referred to as Doppler shift and it can be defined as a change in wave frequency with respect to an observer who is moving relative to a wave source. Thus, it is an effect that is caused by a moving wave source with an apparent upward shift in frequency with respect to an observer.

In Astronomy, the Doppler effect is best used for detecting large extrasolar planets that are orbiting close to their stars, especially by observing the Doppler shifts in the spectrum of its parent star.

Furthermore, orbital period of a planetary body can be determined when the Doppler method is used to measure the period with which a star alternately moves toward and away (radial-velocity) from planet Earth (us) due to an orbiting planet.

Center of mass

Explanation:

The Doppler technique is a good method for discovering exoplanets. It uses the Doppler effect to analyze the motion and properties of the star and planet. Both the planet and the star are orbiting a common center of mass. This means that the star and the planet gravitationally attract one another, causing them to orbit around a point of mass central to both bodies.

sleep paralysis is a parasomnia, events associated with sleep.

sleep paralysis happens when you are in the middle of waking up or falling asleep. it is the feeling of being conscious but unable to move. it definitely involves hallucinations.

i had a friend that had sleep paralysis and he told me a story one time where he was laying in bed and he couldn't move his body no matter how hard he tried and there was someone standing in the corner of his room coming towards him. he couldn't move and you can't "wake up" because you are already conscious. sometimes sleep paralysis can be triggered by frequent waking up during the night based off of multiple trips to the bathroom, or if you had ever been abused, sleep paralysis can start happening from things like that.

answer: i think he can see forward ten seconds and move forward ten seconds but giorno can undo his actions with ger.
