Sort the statements below by placing each in the correct bin True False With the transit method, astronomers can determine the The transit method relies on observing a planet cross in front of a star and mass, temperature, and radius of the star. measuring the resulting drop in light. The radial velocity method uses the spectrum The transit method relies on observing of a star to look for a wobble that would indicate a body in orbit around it the wobble in a host star's spectrum as a planet orbits the star The radial velocity technique can only be used when a planet orbits in our line of sight.

Explanation / Answer

True statements are-

1) The transit method relies on observing a planet cross in front of a star and measuring the resulting drop in light.

2) the transit method relies on observing the wobble in the host star's spectrum as a planet orbits the star.

3) the radical velocity method uses the spectrum of a star to look for a wobble that would indicate a body in orbit around it.

The false statements-

1)with the transit method astronomees can determine the mass temperature and radius of the star. It is wrong because it can be determined for planets not for star.

2) the radical velocity technique can only be used ehen a planet orbits in our line of sight.
