While looking through the Mt. Palomar telescope, you discover a large planetary object orbited by a single moon. The moon orbits the planet every 7.35 hours with the centers of the two objects separated by a distance roughly 2.25 times the radius of the planet. Fellow scientists speculate that the planet is made of mostly iron. In fact, the media has dubbed it the ''Iron Planet'' and NASA has even named it Planet Hephaestus after the Greek god of iron. But you have your doubts. Assuming the planet is spherical and the orbit circular, calculate the density of Planet Hephaestus.
Mercury's orbit ranges from 46 to 70 million km from the Sun, while Earth orbits at about 150 million km.

- Saturn is about 60,000 km in radius, and its rings are only about 0.01 km thick with ripples 100 m high. Design a really big model with Saturn 60 inches in radius (10 ft in diameter). How thick must the rings be in your model and how high can the ripples be? A sheet of paper is about 0.004 inches thick.arrow_forwardWhich of the following statements are true? Choose all that apply. If light from a star passes through an exoplanet's atmosphere, we can look at the absorption spectra to determine what elements & compounds are in the atmosphere. For a telescope, increasing fe will decrease the actual size of the image seen by the person looking through the telescope. In crown glass, the index of refraction for red light is 1.512 and for orange light it is 1.514. Thus in crown glass, red light is faster than orange light. If unpolarized light is incident on a polarizer, 50% will pass through. The glasses for nearsighted people create real images for them to see. The smaller the diameter of an optic is, the larger the minimum angle it can discern is.arrow_forwardWhat is the angular diameter of Saturn (in degrees) as seen from the surface of Hyperion? (Note: Necessary data can be found https://www.webassign.net/seedsfoundations14/22-celestial-profile-saturn.pdf and in this table https://www.webassign.net/seedsfoundations14/a-table-11.pdf)( Hint: Use the small-angle formula) _________ degreesarrow_forward
- The Readouts panel states that your field of view is 1.22°. That means that you are looking at a 1.22° diameter circular section of the night sky. If the image of Saturn (without rings) takes up about 4.25% of this field of view, calculate the size (in degrees AND arcseconds) of Saturn in the field of view.arrow_forwardPhobos, one of Mars’ moons, is very slowly spiraling down towards the planet. Do you think that Mars will one day have rings? Explain your reasoning,arrow_forwardUse the small-angle formula to calculate the angular diameter (in degrees) of Saturn (including its rings) (diameter = 9.64 ✕ 105 km) as seen from Earth if Saturn were at the location of the Moon (distance = 384,000 km).arrow_forward
- Which of the following statements are true? Choose all that apply. If light from a star passes through an exoplanet's atmosphere, we can look at the absorption spectra to determine what elements & compounds are in the atmosphere. The reason astronomers want telescopes with large primary mirrors is to gather as much light as possible. In crown glass, the index of refraction for red light is 1.512 and for yellow light it is 1.518. Thus in crown glass, red light is slower than yellow light. If the axes of two polarizers are anti-parallel to each other, then no light will get through. The glasses for nearsighted people create real images for them to see. The larger the diameter of an optic is, the smaller the minimum angle it can discern is.arrow_forwardWhich of these things did the Voyager spacecraft discover about Enceladus in the early 1980s, indicating that it is somewhat unusual among planetary bodies in our solar system? Check the TWO items that apply. a It has a thick atmosphere, made mostly of nitrogen. b It has the darkest, least reflective surface of all the known planetary bodies. c It is the brightest (i.e. most reflective) object in the solar system. d The entire surface is more heavily-cratered than any other body in our solar system. e Its surface is very smooth in some places.arrow_forwardYou are making a scale model to visualize the relative sizes of the planets in our solar system. The scale of the model is: 1 cm = 2000 km. The radius of Saturn is 60,000 km. At what radius will Saturn appear on your scale model?arrow_forward
- 1- MODIS is an Earth Observation sensor onboard TERRA spacecraft flying in a near-polar circular orbit with an orbital period of 98.8 minutes. The width of the swath imaged by MODIS is 2330 km. A- How many orbits does TERRA trace in one day? B- Assuming that the Earth rotates around its polar axis at a rate of 0.2618 rd/hr and that the equatorial radius is 6378 km, do two consecutive swaths of MODIS overlap at the equator? (hint: the length of an arc = angle in rd * radius) C- The radius of the latitude circle at 35 deg is 5224.5 km. Do two consecutive swaths of MODIS overlap at latitude 35 deg? 2- An aerostationary orbit for Mars is equivalent to a geostationary orbit for Earth. It is designed to enable a satellite in that orbit to image always the same surface of Mars. Calculate the altitude of an aerostationary orbit assuming that Mars is spherical, that its sidereal rotational period is 1.02595676 Earth days, its equatorial radius is 3389.50 km and its mass is…arrow_forwardNASA Scientists want to measure the current distance between two of Jupiter's Moons, Ganymede and Europa. They set up a laser on the surface of Ganymede, shine it at a mirror on the surface of Europa and measure how long it takes for the laser light to return to a detector on the surface of Ganymede. They calculated the current distance between the two moons to be 787 million meters. How long did it take the light to make it to Europa and back? *Give answers to at least three significant figures. DO NOT submit answers in scientific notation. Use symbols for units (i.e. m, s, kg, N)*arrow_forwardSaturn’s A, B, and C Rings extend 75,000 to 137,000 km from the center of the planet. Use Kepler’s third law to calculate the difference between how long a particle at the inner edge and a particle at the outer edge of the three-ring system would take to revolve about the planet. Enter the value you get from the ratio of the period of the inner edge to the outer edge of the rings.arrow_forward
