Are circles orbits of the planets?
NO!!! The planets do NOT orbit in circles. They orbit the Sun in an ellipsoidal manner. An ellipse has two foci. The Sun lies at one of the foci, the other might be deemed to be a 'blind' focus. The Sun does NOT lie at the centre of the ellipse. Also the satellites(moons) orbit their parent planets in a similar manner. It has also been discovered that the planets in an an ellipsoidal manner. That is as each orbit is completed the planet 'over-shoot' their starting point, and the ellipse does not close . See Johannes Kepler, who gave us the Law of orbiting planets sweeping equal arcs in equal times , in 1602 AD.

What model states that the earth is at the center of the solar system and all planets orbit the eartg?
The model that states the Earth is at the center of the solar system, with all planets orbiting it, is called the geocentric model. This view was historically championed by astronomers like Claudius Ptolemy in the 2nd century AD. It was widely accepted until the heliocentric model, proposed by Nicolaus Copernicus, demonstrated that the Sun is at the center of the solar system, leading to a fundamental shift in our understanding of celestial mechanics.
What year did the Mayan people build an observatory for viewing the stars and planets at Chichen Itza in Mexico?
The Mayans built the observatory known as El Caracol at Chichen Itza in Mexico around the 9th century AD. This structure served as a viewing platform for observing celestial events such as the movement of stars and planets.
