The planet below is orbiting the Sun. The two sweeps are on opposite sides of the Sun and are labeled t. Though the orbital distance covered in each sweep is different, the time interval for each sweep is the same. Areas A and B are bounded by the arcs of the planet’s sweep in time, t, and the lines between the endpoints of the arc and the center of the Sun. What can you infer about the two areas?

• Area A is 50% smaller than Area B.

• Area A is twice as big as Area B.

• Area A is the same size as Area B.

• Area A is 50% larger than Area B.

A new planet is discovered orbiting a single star. The planet has one moon. According to Kepler’s First Law, what do scientists know about the orbit of the planet around the star?

• The orbit is circular with the star at the center of the circle.

• The orbit is elliptical with the star at one focus of the ellipse.

• The planet orbits the star in a direction opposite to the direction of the moon’s orbit of the planet.

• The planet takes 12 times longer to orbit the star than the moon takes to orbit the planet.

• They are millions of light-years apart.

• Most can be seen without a telescope.

• Space contains several billion galaxies.

• They contain millions of stars.

On a clear night away from city lights, a band of light is easily observed in the night sky. Which statement best identifies this band of light?

• It is a nearby galaxy known as the Andromeda galaxy.

• It is the Milky Way galaxy as seen from the inside.
