Astronomers use the coordinate system of RA right ascension also called hour angle, and Declination (Dec)RA is the celestial equivalent of terrestrial longitude. Both RA and longitude measure an east-west angle along the equator; and both measure from a zero point on the equator. For longitude, the zero point is the Prime Meridian; for RA, the zero point is known as the First Point of Aries, which is the place in the sky where the Sun crosses the celestial equator at the March equinox. RA is always zero on the meridian of the celestial sphere which passes through the celestial poles and first point of Aries. Declination is comparable to latitude, projected onto the celestial sphere, and is measured in degrees north and south of thecelestial equator. Therefore, points north of the celestial equator have positive declinations, while those to the south have negative declinations. * An object on the celestial equator has a dec of 0°. * An object at the celestial north pole has a dec of +90°. * An object at the celestial south pole has a dec of −90°.
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.
Large stars are distributed all over our galaxy, there is no single location for them.
The visibility of stars is primarily determined by factors such as light pollution, atmospheric conditions, and the location on Earth. Light pollution from artificial sources can overwhelm the faint light of stars, while atmospheric conditions like clouds or humidity can block starlight. Additionally, stars are more visible in areas with minimal light pollution, such as rural locations or remote areas.
The temperature of a star can be determined from its color. Stars with cooler temperatures appear red, while stars with hotter temperatures appear blue. This color-temperature relationship is known as the Wien's Law.
...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.
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.
These days, an instrument called a "Sextant". Before Columbus, an "Astrolabe".
No. The color is determined by the star's temperature, not location.
The tomb of Saint Peter determined the location of St. Peter's Basilica.
