Exam 5: The Architecture and Birth of Planetary Systems

The most successful method to date in determining an exoplanet's radius is:

The figure below shows two stars.Star A has a mass twice that of our Sun,while Star B has a mass four times that of our Sun.Which labeled point identifies the center of mass of the system?

Arrange the following objects in order of increasing distance from the Sun:

Venus is unusual within the Solar System because it:

The density of a terrestrial planet is an imperfect indicator of its location in the Solar System because:

Binary accretion describes the:

Astronomers discover an icy body in our Solar System with a radius of 10,000 km traveling on a circular orbit.It is most likely to be a(n):

Why are planetary systems disks with rapid rotation if they begin their lives as spherical,slowly rotating gas clouds?

A body passing through Earth's atmosphere that creates a streak of light in the sky is a:

A comet with an orbit near the ecliptic plane and an orbital period of 75 years most likely comes from the:

Suppose Jupiter's gravity disturbs an asteroid and sends it on an elliptical orbit with a high eccentricity.If the semimajor axis of the resulting orbit is 2 AU,the object would be classified as a(n):

What is a dwarf planet?

The coma of a comet glows because:

Explain the differences between meteoroids,meteorites,and meteors.

What property of the protoplanetary disk was most responsible for differentiation between the planets?

Dust grains form within a protoplanetary disk because:

The majority of meteoroids are most similar to:

How do terrestrial planets form?

An asteroid follows a highly elliptical orbit that carries it into the inner Solar System.What could eventually happen to it?

The figure below shows the orbits of the planets within the Solar System as well as the orbits of three other objects labeled A,B,and C.Based on their orbits,of what parts of the Solar System are objects A,B,and C part?
