- Mars has the largest volcanoes in the solar system. (T/F)Not including technology and instruments, give 2 reasons why our knowledge of the solar system has increased considerably in the past few years.A small cloud in Jupiter's equatorial region is observed to be at 120.80 ° west longitude in a coordinate system that rotates at the same rate as the deep interior of the planet. Another observation made exactly 9.50 Earth hours later finds the cloud at 119.60 ° west longitude. Jupiter's equatorial radius is 71,500 km. What is the observed equatorial wind speed in kilometers per hour?
- At an average opposition, the Earth and Mars are separated by 0.52 AU. Suppose an astronomer observes Mars at opposition and that seeing blurs the images to a resolution of 1.0 seconds of arc. What is the smallest surface feature the astronomer would be able to resolve on Mars? How does this size compare with the diameter of Mars?Phobos, 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,Why is Mars red?
- equattion : S/4 (1- a) = f*sigma*TS4 Solar Constant (W/m2) S = 1361 How sensitive is the temperature of the earth to changes in the atmospheric transmissivity (f)? The atmosphere is more transmissive (lets more radiation through) when CO2 and other greenhouse gases are lower. During the pre-industrial period, transmissivity (f) was probably around 62% (f = 0.62) and has been decreasing. Calculate how much the Earth's surface temperature would change if the transmissivity changes by ±0.01 (to 0.60 or to 0.62). ___ °C per 1% transmissivity change.The planet Uranus was discovered in 1781, and Neptune, the next planet outward from the Sun, was discovered in 1846. Imagine you're an astronomer in 1846, and you start wondering if there's another planet out beyond Neptune. You decide to try and discover its existence using the same method that was used for Neptune. How will you do this? Group of answer choices You'll recruit a large number of astronomers to use their telescopes to carefully scan the sky in directions that are far from the ecliptic. The regions around the north and south celestial poles will probably be the best "hunting grounds" for the new planet. You'll examine Uranus and Neptune very carefully, on every clear night, for several years, to see if you can find any evidence that sunlight has been reflected off of the `new' planet, then off of Uranus or Neptune, before arriving on Earth. On rare occasions when Neptune passes in front of the Sun, as seen from Earth, you'll look carefully at the Sun (with a safe…Out of the inner planets in the solar system (Mercury, Venus and Mar) which do you think is the most likely to be colonized? Explain why?
- (b) Show that the equilibrium temperature of Venus is right for liquid water, given that it lies = 3.85 × 1026 W) and assuming a at a distance of d = 1.09 × 108 km from the Sun (Lo mean albedo of 0.45. Explain why, in reality, Venus is too hot for liquid water.A newly discovered star was found to have a surface temperature of approximately 5185 K. If an astrologist wanted to look for potentially habitable planets, what is the maximum distance from the star to reach its solar system's 'Goldilocks Zone'?Titan's exosphere has a temperature of about 218 K. What is the thermal speed of hydrogen (in km/s) in Titan's exosphere? The mass of a hydrogen atom is 1.67 × 10-27 kg and Boltzmann's constant is k = 1.38 × 10-23 Joule/Kelvin.
