The location of 850 stars was determined by the Hipparcos satellite, launched by the European Space Agency in 1989. Hipparcos measured the positions, distances, and motions of these stars with very high precision using astrometry techniques. The data collected by Hipparcos significantly advanced our understanding of the structure and dynamics of the Milky Way galaxy.
Hipparchus, an ancient Greek astronomer, measured the positions of around 850 stars.
No, stars appear the same regardless of the country you are in. The appearance of stars is determined by factors such as the atmosphere and light pollution, but these factors are not specific to any one country.
The stars you see in the sky depend on the time of year and your location on Earth. The brightness of the stars, the presence of any natural or artificial light pollution, and atmospheric conditions also influence the visibility of stars in the sky.
To be honest, the number of stars cannot be determined accurately. First, there are too many. Second, we can't see all of them. Some are too far away, some are too dim. We cannot see through the Milky Way, and so an unknown number of stars are hidden behind the galactic core.
For pure clean water at standard temperature and pressure, 850 ml has a mass of 850 grams.
...Is called a sextant, invented 1757.
He is the father of spherical astronomy, by which the location of objects like planets and stars in the universe can be determined.
He counted 850 stars. (That is what my teacher said.)
These days, an instrument called a "Sextant". Before Columbus, an "Astrolabe".
No. The color is determined by the star's temperature, not location.
About 700-850 were saved.
The tomb of Saint Peter determined the location of St. Peter's Basilica.
Your location and and the local weather conditions. The location, distance and luminosity of the stars
Stellar parallax
The temperature of a star can be determined by its color. Hotter stars appear blue/white, while cooler stars appear red.

The mass of a star can be determined from a binary star system, specifically by measuring the orbital motion and interaction between the two stars. This allows astronomers to apply Kepler's laws of planetary motion to calculate the masses of both stars in the system.
