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
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.
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.

Figure 4-11 Tychos model of the Universe retained the first principles of classical astronomy; it was geocentric with the Sun and Moon revolving around Earth, but the planets revolved around the Sun. All motion was along circular paths. Figure 4-16 (a) If Venus moved in an epicycle centered on the Earth-Sun line (see Figure 3b in the Chapter 2 Concept Art: An Ancient Model of the Universe), it would always appear as a crescent.
