Difference between Astronomical unit and Astronomy

Astronomical unit vs. Astronomy

The astronomical unit (symbol: au, ua, or AU) is a unit of length, roughly the distance from Earth to the Sun. Astronomy (from ἀστρονομία) is a natural science that studies celestial objects and phenomena.

Similarities between Astronomical unit and Astronomy

Astronomical unit and Astronomy have 28 things in common (in Unionpedia): Al-Battani, Al-Biruni, Aristarchus of Samos, Astronomy & Astrophysics, Celestial mechanics, Cosmic distance ladder, Earth, Ellipse, General relativity, Hipparchus, Johannes Kepler, Kuiper belt, Mars, Mercury (planet), Milky Way, NASA, Near-Earth object, Nicolaus Copernicus, On the Sizes and Distances (Aristarchus), Oort cloud, Parallax, Photon, Ptolemy, Solar System, Star system, Sun, The Astrophysical Journal, Venus.

Al-Battani

Abū ʿAbd Allāh Muḥammad ibn Jābir ibn Sinān al-Raqqī al-Ḥarrānī aṣ-Ṣābiʾ al-Battānī (Arabic: محمد بن جابر بن سنان البتاني) (Latinized as Albategnius, Albategni or Albatenius) (c. 858 – 929) was an Arab astronomer, astrologer, and mathematician.

Aristarchus of Samos

Aristarchus of Samos (Ἀρίσταρχος ὁ Σάμιος, Aristarkhos ho Samios; c. 310 – c. 230 BC) was an ancient Greek astronomer and mathematician who presented the first known model that placed the Sun at the center of the known universe with the Earth revolving around it (see Solar system).

Nicolaus Copernicus

Nicolaus Copernicus (Mikołaj Kopernik; Nikolaus Kopernikus; Niklas Koppernigk; 19 February 1473 – 24 May 1543) was a Renaissance-era mathematician and astronomer who formulated a model of the universe that placed the Sun rather than the Earth at the center of the universe, likely independently of Aristarchus of Samos, who had formulated such a model some eighteen centuries earlier.
