The stars and three of the planets were discovered in about 27,000 BC by Professor Ughhh the Caveman when he happened to be out of his cave at nightfall. They are, after all, pretty obvious to anybody who looks up in the evening or before dawn.
The ancient Babylonians and Egyptians were careful observers of the night sky, and by the time of the Greeks, had cataloged most of the brighter stars and the five "visible" planets. The earliest known star atlas was the Almagest of Claudius Ptolemy, a Roman citizen who lived in Alexandria, Egypt. (The Almagest refers to earlier catalogs which have not survived the intervening 2000 years.)
What else can I help you with?
The reason that most extrasolar planets are found close to their parent stars?
Most extrasolar planets are found close to their parent stars because current planet detection methods are biased towards detecting larger planets that are closer to their stars due to the limitations of technology. These close-in planets are easier to detect because they have a greater impact on their star's light or motion. As technology and detection methods improve, we are discovering more distant planets from their stars.
Do stars orbit planets or planets orbit stars?
Planets orbit stars.
Do planets and moons have stars?
On the contrary! A star has planets, which circulate it. And planets have moons. Stars do not circle planets.
What do astronomists do?
Astronomers study celestial bodies such as stars, planets, galaxies, and black holes. They conduct research to understand the origins and evolution of the universe, often using telescopes and computer simulations to analyze data. They also contribute to our knowledge of important concepts like gravity, dark matter, and the expansion of the universe.
Who used a telescope to make detailed observations of the stars ad planets?
Galileo Galilei used a telescope to make detailed observations of the stars and planets. He is most well known for suggesting that the Earth revolves around the Sun, and not the other way around.
Which pulling force do planets and stars have?
Planets and stars have gravity.
What makes stars and planets?
The Solar System Makes the planets and the Stars.
Do the stars orbit the planets or do planets orbit stars?
Moons orbit planets. Planets orbit stars. Some stars orbit other stars, or orbit their mutual center of gravity. Stars orbit the center of the galaxy. Galaxies may orbit the center of the "galactic group".
How are astronomists different from astrologists?
Astronomy is the scientific study of the Universe: what is out there in space, how old the Universe is, what will be its future, etc. Astrology is a set of beliefs about mysterious influences the stars or planets have on us. This is not based on any scientific method, and is really just superstition. By the way, the people who study each of the discipline would be called "astronomers" and "astrologers"
Is stars planets?
No. Stars are like suns, around which planets may orbit.
Who studies stars and planets?
Astronomers (and their ilk) study stars and planets.
Can planets and stars orbit around the sun?
Planets orbit the sun. Stars do not.
