What is the Antares absolute magnitude and its apparent magnitude?
Antares Absolute and Apparent Magnitude Absolute Magnitude~ -5.2 Apparent Magnitude~ +0.60
What are the release dates for The Heir Apparent - 2014?
The Heir Apparent - 2014 was released on: USA: 1 September 2014
What is the difference between apparent magnitude and surface magnitude?
The two types are apparent magnitude, the magnitude of a star as it appears to us, and absolute magnitude, which is what a star's apparent magnitude would be at a standard distance of ten parsecs.
What is a synonym for absolute magnitude and apparent magnitude?
Apparent magnitude: How bright something looks to us. Absolute magnitude: How bright something really is - expressed as the apparent magnitude it would have at a standard distance.
Who reinvented or rediscovered the heliocentric theory?
The original idea (at least, the earliest of which we're aware) that the Earth circled the Sun was proposed by Aristarchus of Samos, a Greek astronomer and mathematician. But the Aristotle's idea that the Sun circled the Earth was more "obviously apparent" and became accepted as fact. The reintroduction of the heliocentric theory by Copernicus, supported by more accurate celestial observations, came almost 1700 years later.
What is an apparent magnitude?
Earth's apparent magnitude would depend on where it is viewed from. For instance, from Saturn, the apparent magnitude is 1.45. From Mars is would be somewhat higher.
What is the line that the sun traces across the celestial sphere?
The "ecliptic". In truth, the Sun doesn't move; the apparent motion of the Sun across the sky is caused by the Earth spinning, and the apparent motion of the Sun across the "celestial sphere" is caused by the Earth orbiting the Sun. But the plane of the Earth's orbit around the Sun is what causes the apparent motion of the Sun across the celestial sphere, so the "ecliptic" is actually the plane of the Earth's orbit.
How solstices and equinoxes different?
Equinoxes are the two points among the stars where the sun's apparent annual path crosses the celestial equator. Solstices are the two points among the stars where the sun's apparent annual path reaches its extremes, north and south of the celestial equator.
What is the apparent movement of an object across a background when observed from two different places?
Parallax is the apparent movement of an object across a background when observed from two different places.
Why there are seasons and the apparent motion of the stars and sun?
The seasons are due to axial tilts of planets and the apparent motion of stars and sun on the celestial sphere is due to diurnal motion.
What are the two day of the year on which the sun reaches its greatest distance north or south of the equator?
June 21:Sun at solstice, farthest apparent distance north of terrestrial and celestial equators.December 21:Sun at solstice, farthest apparent distance south of terrestrial and celestial equators.
Why does the sun have the greatest apparent magnitude of any celestial object of the sky?
The sun appears to be the largest celestial body in the sky, as it's fairly close to earth, and it's extremely large - in comparison with other celestial bodies e.g. the moon.
What are the two days of the year on which h the sun reaches its greatest distance north or south of the equator?
June 21:Sun at solstice, farthest apparent distance north of terrestrial and celestial equators.December 21:Sun at solstice, farthest apparent distance south of terrestrial and celestial equators.
What is The apparent change in position of an object with respect with respect to a distant background is called?
Parallax id the apparent shift in position of an object with respect to the background due to a shift in view point.
What is responsible for the patterns of motion of all celestial objects?
Gravity for the real motion, the Earth's rotation for the apparent motion.
What is the sun's apparent path through the background of stars called?
ecliptic
What is the Eliptic?
Look up ecliptic, thats what you or another person misspelled
