In Lecture 4, we discussed Kepler’s third law relatingthe orbital period of a planet (p) to the semi-major axis (orbital distance, a) of its orbit(p2= a3). We can apply this law as long the object orbits the Sun or another object of the same mass, and the units of orbital period are in (Earth) years and the orbital distance is in Astronomical Units(AU). [1AU is equal to the distance between the Earth and the Sun]. [Note: Newton extended this law...

A planet was discovered orbiting a star at a distance of 2870 million km with an orbital period of about 84 years (1 year = 365.25 days). What is the mass of the star?

A new planet is discovered orbiting our sun at a distance of 5.7 AU. An AU (astronomical unit), is defined as the distance from the sun to the earth, or 149.6 million kilometers. How many days would a year on this new planet be?

Tau Ceti is a star that is located 11.753 ly away. There
is a planet orbiting this star with an orbital radius of 0.538 AU
(AU stands for astronimcal unit - the average distance between
Earth & the Sun). Fill in the table below by determining the
minimum diameter the objective of a telescope would need to be in
order to resolve the planet from the star at the stated
wavelengths. 1 ly = 9.461 × 1015 m & 1...

Each of the following diagrams shows a planet orbiting a star. Each diagram is labeled with the planet's mass (in Earth masses) and its average orbital distance (in AU). Assume that all four stars are identical. Use Kepler's third law to rank the planets from left to right based on their orbital periods, from longest to shortest. If you think that two (or more) of the diagrams should be ranked as equal, drag one on top of the other(s) to...

A planet is discovered to orbit around a star in the galaxy Andromeda, with the same orbital diameter as the Earth around our Sun. If that star has 4 times the mass of our Sun, what will the period of revolution of that new planet be, compared to the Earth's orb o One-fourth as much o One-half as much Twice as much A. Four times much The average distance from the Earth to the Sun is defined as one "astronomical...

A newly discovered planet orbits a distant star with the same mass as the Sun at an average distance of 109 million kilometers. Its orbital eccentricity is 0.5. Find the planet's orbital period. Find the planet's nearest orbital distance from its star. Find the planet's farthest orbital distance from its star.

(a) An asteroid is in an elliptical orbit around a distant star. At its closest approach, the asteroid is 0.700 AU from the star and has a speed of 54.0 km/s. When the asteroid is at its farthest distance from the star of 36.0 AU, what is its speed (in km/s)? (1 AU is the average distance from the Earth to the Sun and is equal to 1.496 x 101 m. You may assume that other planets and smaller objects...

An exoplanet is in an elliptical orbit around a distant star. At its closest approach, the exoplanet is 0.530 AU from the star and has a speed of 54.0 km/s. When the exoplanet is at its farthest distance from the star of 33.0 AU, what is its speed (in km/s)? (1 AU is the average distance from the Earth to the Sun and is equal to 1.496 ✕ 1011 m. You may assume that other planets and smaller objects in...
