- What would be the advantage of making parallax measurements from Pluto rather than from Earth? Would there be a disadvantage?arrow_forwardAs seen from Earth, the Sun has an apparent magnitude of about 26.7 . What is the apparent magnitude of the Sun as seen from Saturn, about 10 AU away? (Remember that one AU is the distance from Earth to the Sun and that the brightness decreases as the inverse square of the distance.) Would the Sun still be the brightest star in the sky?arrow_forwardAn exoplanetary system has two known planets. Planet X orbits in 290 days and Planet Y orbits in 145 days. Which planet is closest to its host star? If the star has the same mass as the Sun, what is the semi-major axis of the orbits for Planets X and Y?arrow_forward
- From Doppler shifts of the spectral lines in the light coming from the east and west edges of the Sun, astronomers find that the radial velocities of the two edges differ by about 4 km/s, meaning that the Sun’s rotation rate is 2 km/s. Find the approximate period of rotation of the Sun in days. The circumference of a sphere is given by 2pR, where R is the radius of the sphere.arrow_forwardConsidering that Earth experiences an average intensity of sunlight of 1330 W/m? and is at a distance from the Sun of 1.0 AU = 150 million km, and considering that that the apparent magnitude of the Sun as seen from Earth is m = -26.7, (a) then how far from the Sun would a distant Kuiper- belt world need to be in order for the apparent magnitude of the Sun to be m = -11.0 as seen on that world? Give your answer in AU. (b) What would be the orbital period of this world? Give your answer in Earth years.arrow_forwardA certain binary system consists of two stars that have equal masses and revolve in circular orbits around a fixed point half-way between them. If the orbital velocity of each star is v=186 km/s and the orbital period of each is 11.3 days, calculate the mass M of each star. Give your answer in units of the solar mass, 1.99×1030 kg (e.g. if each planet's mass is 3.98×1030 kg, you would answer "2.00").arrow_forward

Assuming Mercury follows a circular orbit with a semi-major axis = 0.387 AU and a period = 88 days, calculate the maximum %3D stellar aberration that would be detected, expressing your answer in arcseconds. Choose the option below that best matches your answer.

It is exactly as far away from its star as Earth is to its own Sun. Draw a FBD, then determine how many times more or less massive this star is than our sun (in other words, give a factor of mass, e.g “5x larger” or “5x smaller”)arrow_forward
- One way that astronomers detect planets outside of our solar system (called exoplanets) is commonly referred to as the radial velocity method. This relies on the __________ ___________ to cause shifts in the spectral lines of stars as the stars perform tiny orbits around the center of mass of the host star and its orbiting planets. Those tiny orbits cause the stars to periodically (and therefore predictably) move closer to and further away from our solar system. Luckily, this method only relies on the motion of the star; its physical distance from us does not impact the resulting shifts.arrow_forwardThe figure below shows the radial velocity of a star plotted as a function of time over the course of 20 days. Where is the planet in its orbit around the star when the star's radial velocity is 18 km/s? How do I determine this?arrow_forwardLight takes about 8.3 minutes to travel from the Sun to Earth. When it is closest, Neptune is 30.0 times farther from Earth than the Sun is. Make a prediction: Should light take more or less time to reach Earth from Neptune than from the Sun?arrow_forward
