They observe how much it shifts against the background of other background stars when viewed from either side of Earth annual orbit of the Sun. Knowing the diameter of this orbit they can then work out the distance by triangulation.
For a small amount of time but later left after about 2 months or so...
The movie 28 Months Later has not been created as of yet. The movie would be the sequel to 29 Weeks Later that was released on May 11, 2007.
The name "Nova" is used in two senses, both because Nova is a science program. Nova means "new" in its original sense and was later adopted by astronomers to describe a bright, exploding star.
Chaldean astronomers developed early forms of astronomy and mathematical concepts, including the division of the zodiac into twelve signs and the creation of a lunar calendar. They made significant contributions to understanding celestial phenomena, such as eclipses and planetary movements. Their observations laid the groundwork for later astronomical advancements in ancient Greece and beyond. Additionally, they are credited with the development of a base-60 number system, which influenced timekeeping and geometry.
James earl ray was caught in Europe two months later and sentenced 99 years in prison where he later died on April 23, 1998 from liver failure.
Astronomers use a method called parallax to measure the distance to nearby stars. By observing how a star's position changes when viewed from different points in Earth's orbit around the Sun, astronomers can calculate the star's distance based on the angle of this apparent shift.

The easiest way is to look at a picture of the star and then look at another one taken six months later. If it has moved, that can be seen on the photo when you look at it in relation to the stars in the background of the photo. That was the first method used to find the distance to the nearest stars, and it was a big surprise to find out how far they actually were.
Its precision, its accuracy, and its continuity did.

Two months later than what? Two months after sex - no. Two months after abortion - yes Two months after giving birth - maybe

2 months later, that's about April 2 months later, that's about April

The star they were observing, 51 Pegasi, moved back and forth only very slightly. Therefore, they knew the invisible object could not have enough mass to be a star. They deduced that it must be a planet.
It's hard to answer, because the modern science of astronomy blends almost imperceptibly into the ancient pseudoscience of astrology, and that extends back into prehistory. There's not really a date at which you could draw a line and say "nothing before this was astronomy" ... astrologers did do a fair amount of observing and cataloging the heavens, just as astronomers would later do.
