When you look at the moon from earth what do you see?
When you look at the moon from Earth, you see its different phases (full moon, crescent, etc.) as it orbits our planet. You can also observe dark areas called maria, which are ancient lava plains, and bright spots caused by lunar highlands. On a clear night, the moon appears as a bright, round object in the sky.
Who believed that the earth is round and rotates on its axis causing day and night?
Greek philosopher Aristotle believed that the Earth is round and rotates on its axis, causing day and night. He observed that different stars were visible in different parts of the world at the same time, which led him to conclude that the Earth was spherical and rotating.
Is scientific method theorized that planets moved in oval paths around the sun?
The planets and all other objects in the solar system move in elliptical orbits round the Sun. That's a sort of "oval", roughly. The shape of the orbits was discovered by Johannes Kepler and published in 1609. The amount of elongation of an ellipse is measured by a parameter called the eccentricity (a circle is an ellipse with zero eccentricity). In the case of the eight planets (except Mercury) the eccentricity is low and the shape of the orbit is very close to a circle but with the Sun displaced from the centre by an amount equal to the eccentricity multiplied the the average distance (the semimajor axis). Mars has the highest eccentricity of all the eight planets other than Mercury. Mars's orbit has a semimajor axis of 1.524 astronomical units and eccentricity of 0.0934. The minor axis of the ellipse is 99.6% of the major axis, so the orbit looks like a circle, but the centre of the circle is 0.142 astronomical units away from the Sun, so Mars's distance varies from 1.382 to 1.666 astronomical units. Kepler's achievement in discovering that Mars's orbit is an ellipse rather than the offset-circle used in the Ptolemy theory is highly impressive and it depended on the very accurate observations and measurements made by his employer, Tycho Brahe.
What are the differences between the Arctic and the Antarctic Circles?
The Arctic Circle is located in the Northern Hemisphere, while the Antarctic Circle is in the Southern Hemisphere. The Arctic Circle surrounds the North Pole, while the Antarctic Circle surrounds the South Pole. The Arctic Circle has Arctic tundra vegetation, while the Antarctic Circle is largely covered in ice.
What is the eccintricity of a circle?
A circle has no eccentricity because it is a perfectly symmetrical shape. The eccentricity of a shape is a measure of how much its shape deviates from being a perfect circle, so for a circle, the eccentricity is always zero.

How is the Mayan calendar similar to the Miami circle?
The Mayan calendar is a system for tracking time used by the ancient Mayan civilization, while the Miami Circle is a mysterious archaeological site in Florida consisting of a perfect circle of holes carved into limestone. Both the Mayan calendar and the Miami Circle represent aspects of ancient cultures' understanding of time, astronomy, and spiritual beliefs, although they are not directly related in terms of function or purpose.
What is the astronomical symbol for Uranus?

Does it get darker than astronomical twilight at night in every Northern Hemisphere location south of the Arctic Circle in December?
Yes, absolutely. At the Arctic Circle in December, it barely gets LIGHT enough to be astronomical twilight. Then it gets dark again.
What is an Aureole?

What is the astronomical sign of mercury?
