The Mars Reconnaissance Orbiter
(MRO) flies at an average altitude of 280km above the Martian Surface.
If its cameras have an angular resolution of 0.2 arc seconds, what is the
size of the smallest objects that the
MRO
can detect on the Martian surface?
Use the
equation:
S =x × d / 206265 arcseconds / radian
, where S is the true size of the object, d is the distance from the detector to the object, and x is the angular size of the object. Your answer will be in km (you can
ignore the radians unit (it should appear, but the equation made a simplifying assumption that dropped it out.

- You have a radio telescope that you are designing to observe the fine details of the ring of hydrogen around Jupiter (yes, Jupiter does have rings, but not as pretty as Saturn.) Jupiter is about 5.93E8 km from Earth.

One day, a scientific rumor begins circulating that there is a Jupiter-sized planet around Alpha Centauri, 4.28 light-years away. Your professor has access to viewing privileges for the Hubble Space Telescope (aperture diameter 2.4 m, 100 nm to 2 400 nm), the Hale Telescope on Palomar Mountain in California (aperture diameter 5.08 m, visible light), the Keck Telescope on Mauna Lea, Hawaii (aperture diameter 10.0 m, visible light), and the Arecibo Radio Telescope in Puerto Rico (aperture diameter 305 m, 75-cm radio waves).

Use Stellarium to find the distance to the planet when Skynet took any of your images, in AU. Answer: 4.322 AU Use this equation to determine a conversion factor from 1 arcsecond to AU at the planet's distance. You will need to convert ? = 1 arcsecond to degrees first. Answer: 2.096e-5 AU (2 x 3.14 x 4.322 x (.000278/360) = 2.096e-5) Next, use this number to convert your measurement of the moon's orbital semi-major axis from arcseconds to AU. A) Calculate a in AU. B) Convert your measurement of the moon's orbital period from days to years. C) By Newton's form of Kepler's third law, calculate the mass of the planet. D) Finally, convert the planet's mass to Earth masses: 1 solar mass = 333,000 Earth masses.arrow_forward5. The two images below show a portion of the Trifid Nebula.
