QUESTION 1 5 points What causes Saturn to be a bit squashed

QUESTION 1 5 points What causes Saturn to be a bit squashed at its poles while fatter at the equator? A. Saturn is in a fast orbit around the Sun. O B. The planet spins very fast. C. Saturn is affected by tides from moons. D. Gravity is squashing the planet QUESTION 2 5 points Saved What aspect of the orbit of Neptune\'s largest moon, Triton, indicates it was probably a captured object that did not originally orbit around Neptune? A. It spins the wrong way on its axis. B. It is upside-down. C. It is surprisingly close to Neptune. D.Its orbit around Neptune is elliptical. O E. It orbits around Neptune backwards OF It is tipped on its side. QUESTION 3 5 points Saved A lot of exoplanets are found orbiting other stars by watching the Doppler shift of lines in a star\'s spectrum. From looking at the timing and strengths of the shifts, astronomers can fairly directly determine two properties of the planet: One is the orbital period. The other is what? A Age of the planet B. Planet\'s diameter ° C. Planet\'s composition O D. Planet\'s mass

Solution

Q1. The planet spins very fast.

Saturn\'s day last for 10hr. Dur to fast spinning the gravity flatten the pole and concentrate mass at equator.

Q2. It orbits around Neptune backwards.

The moon orbits is opposite direction of the planet\'s rotation which is not case with any other moons of other planets.

Q3. Planet\'s mass

Using the radial velocity found from Doppler effect the calculated mass can be found.

Q4. It uses mirror to focus light.

Spherical aberration occurs in refractive telescopes. Galileo first used refractive telescope.
