Chapter 5 1. The method of discovering exoplanets by measuring stellar radical velocities relies on the fact that a star does not remain completely stable when a planet orbits it. It very slightly moves in an eclipse or small circle. 2. The method of discovering exoplanets by observing stellar motion works because the planet’s usually causes the star to wobble across the celestial sphere when a star and it’s planet are moving across the sky. 3. If there is often a dimness seen when observing a star, it reveal the presence of a planet. 4. Albert Einstein's theory of relativity shows that matter warps its surrounding space, causing passing light to change direction. This phenomenon is quite analogous to have light passing through a lens, changes direction, and is focused. Light can be focused by

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
