Copernicus was the first person to suggest that the Sun is at
the center of our solar system.
True
False
How did Copernicus figure out which planets were closer to the
Sun and which were further?
the small angle equation
sidereal and synodic periods
shadows on the Earth
Newton's Law of Gravity

Given that the Sun moves in a circular orbit of radius 8.09 kpc
around the center of the Milky Way, and its orbital speed is 216
km/sec, work out how long it takes the Sun to complete one orbit of
the Galaxy. How many orbits has the Sun completed in the 4.5
billion years since it formed?
____ × 108 years
_____ orbits

A planet is in a circular orbit around the sun. Use Newton's law
of gravity and his second law of motion to calculate the period of
the planet (in day). Data: Mass of sun = 1.989 e+30 kg; Mass of
planet = 6.0 e+24 kg; Orbit radius = 1.496 e+11 m.

Imagine that someone discovers an alien spaceship in a perfectly
circular orbit at exactly 4 AU from our Sun. Now imagine that in
response, we scramble to assemble a spaceship of our own in low
Earth orbit. Our spaceship has an orbital speed around Earth of
about 7 km/s, while Earth is moving around the Sun at about 30
km/s.
a. How long does it take the alien spaceship to go around the
Sun once?
b. Which of the following...

Planet Yoyo is discovered to orbit around a star with 5 times
the mass of our Sun. It orbits at a distance of 7 AU in a circular
orbit. The orbital period is measured to be 8 years. Find:
1) The mass of the planet. Give the answer in both solar masses
and kilograms
2) The mass of the star in kilograms
3) The distance of the planets orbit in meters.
4) The force due to gravity between the planet...

Could you find the Mass of the Sun using the slope of the of
T2 versus a3, using the values that are in
units of years and AU? Explain.
Suppose we discovered a planetary body orbiting our Sun at a
distance of 15 AU. How long would this world take to complete one
orbit around the Sun? (show your work)
Suppose Astronomers noticed a moon around the newly discovered
planet in Question 2. By watching this moon, noting its period...

1).
a). An asteroid is discovered in a nearly circular orbit around
the Sun, with an orbital radius that is 2.83 times Earth's. What is
the asteroid's orbital period ?, its "year," in terms of Earth
years?
b). An artificial satellite is in a circular orbit ?=390.0 km
above the surface of a planet of radius ?=3.65×103 km.
The period of revolution of the satellite around the planet is
?=3.15 hours. What is the average density of the planet?

An extrasolar planet in orbit around a Sun-like star is
discovered using the Doppler wobble method. Based on the shape of
the radial velocity curve, the orbit is circular. The data are as
follows. Maximum velocity of the star: 6.3 meters / second Orbital
period: 541 days What is the mass of the extrasolar planet? Give
your answer in units of Jupiter masses.
