In 1676, the Danish astronomer O. Römer first determined the speed of light from observations of eclipses of Jupiter’s moon Io. The position of the satellites is “delayed” by 16.7 minutes, when the observer, together with the Earth, moves to the opposite side of the orbit from Jupiter.
The phenomenon of stellar aberration caused by the Earth’s orbiting the Sun was also used in 1727 by the English astronomer Bradley to determine the speed of light.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
