NASA is sending a probe to Alpha Centauri and then to Sirius. A problem with the probe is noticed while it is at Alpha Centauri, so it must go back to Earth before going to Sirius. Alpha Centauri is 4.3 light-years away from Earth and Sirius is 8.6 light-years away. The probe is traveling at 18.03 km/s, there are 9.461 x 10 meters in one light-year, and there are 1.58125 x 10 light-years in one astronomical unit. How long will the probe have been traveling from when it first leaves Earth to when it arrives at Sirius? Given the above problem, which of these expressions will most likely be your student's first correct step? a) 40.6823 x 1015 m + 81.3646 x 1015 m b) 4.06823 x 10 m + 8.13646 x 10° m c) 81.3646 x 1016 m + 81.3646 x 1015 m d) 8.13646 x 10 m + 8.13646 x 1016 m e) Answer is not there

An astronomer on a planet orbiting the star Deneb wants to differentiate the reflected light by Earth from the light of the Sun. First, consider the area of Earth's disk which reflects the Sun's intercepted light. Second, consider the surface area of a sphere with the same radius as Earth’s orbit around the Sun. Take the ratio of these two areas. Assume the Earth's radius is 6200.0 km and is 1.5 × 108 km from the Sun.

One important goal of astronomers is to have a telescope inspace that can resolve planets like the earth orbiting other stars. If aplanet orbits its star at a distance of 1.5 * 10^11 m (the radius of theearth’s orbit around the sun) and the telescope has a mirror of diameter8.0 m, how far from the telescope could the star and its planet be if thewavelength used was (a) 690 nm and (b) 1400 nm? Use the Rayleighcriterion and give your answers in light-years (1 ly = 9.46 * 1015 m).

The nearest neutron star (a collated star made primarily of neutrons) is about 3.00 1018 m away from Earth. Given that the Milky Way galaxy (Fig. P1.81) is roughly a disk of diameter 1021 m and thickness 1019 m, estimate the number of neutron stars in the Milky Way to the nearest order of magnitude. Figure P1.81
Gaia will have greatly improved precision over the measurements of Hipparcos. The average uncertainty for most Gaia parallaxes will be about 50 microarcsec, or 0.00005 arcsec. How many times better than Hipparcos (see Exercise 19.32) is this precision?
