A planet revolves around a certain star. At one point in the planet's orbit, called periapsis, it passes much closer to the star. Which of the following statements about periapsis is true?
The planet's orbital period becomes shorter after every periapsis.
The planet's orbital period becomes longer after every periapsis.
The planet orbits with a slower speed during periapsis.
The planet orbits with a greater speed during periapsis.
Kepler's 1st law says that our Solar System's planets orbit in ellipses around the Sun where the closest distance to the Sun is called perihelion.
Suppose I tell you that there is a planet with a perihelion distance of 2 AU and a semi-major axis of 1.5 AU.
Does this make physical sense? Explain why or why not.
Suppose, we recently discovered a new planet named Concordia. If for 15 degrees
difference, the distance between Cansae City and and Cantabrigia City would have
been 6050 stadia. According to Erasthosthenes' calculation, what would have been
the circumference of Concordia?
5.45E5 stadia
2.45E5 stadia
4.45E5 stadia
1.45E5 stadia
3.45E5 stadia

However, in modern astronomy, scientists seek to explain the natural and physical world we live in as simply as possible. The complexity of Ptolemy's model was an indicator that his theory was inherently flawed. Why, then, was the geocentric model the leading theory for such a long time, even though the heliocentric model more simply explained the observed motions and brightness of the planets? Check all that apply. ☐ The geocentric model conformed to both the philosophical and religious doctrines of the time. ☐ The heliocentric model did not make noticeably better predictions than the geocentric model. From Earth, all heavenly bodies appeared to circle around a stationary Earth. The complexity of the geocentric model was appealing to most ancient astronomers. Ancient astronomers did not observe stellar parallax, which would have provided evidence in favor of the heliocentric model.arrow_forward
