- The speed of the solar wind is approximately 400 km/s. How many days does the solar wind take to travel from the Sun to Jupiter? (Notes: 1 AU = 1.5 ✕ 108 km;1 day = 86,400 s.)Today, the largest radio telescope in the world is located in Puerto Rico Russia China Australia To be considered habitable, a planet must have an alien civilization living on it the right temperature for liquid water on the surface the right conditions for human explorers to be able to survive a very large iron coreIf the solar nebula hypothesis is correct, do you think there are more planets in the Universe than stars? Why or why not?
- 4) Science fiction movies often portray asteroid belts as crowded, dense regions that require spaceships to maneuver quickly to get through them. In this problem, we will calculate the fraction of volume in an asteroid belt that is actually occupied by asteroids. a) If there are 300,000 large asteroids between 2 and 3 AU from the Sun, and each asteroid is assumed to be spherical with a radius of 100 km, determine the total volume occupied by asteroids in this region. Recall that the volume of a sphere is given by the equation V = 4TR³ /3. b) Let's assume the region in which these asteroids orbit is an annulus with an inner radius of 2 AU, an outer radius of 3 AU, and a thickness of 2Ro. Determine the volume of this region. Recall that the area of a circle is given by the equation A = TR². Here are two conversions that you'll need: 1 AU = 1.496 × 108 km and 1 Ro = 6.955 × 105 km. c) What is the ratio of the volume occupied by asteroids to the volume of the asteroid belt (i.e., the…What is the angular diameter of Saturn (in arc seconds) as seen from Earth when the two planets are closest together? Hint: Use the small-angle formula, angular diameter (in arc seconds) 2.06 x 105 | arc seconds linear diameter distance What is the angular diameter of Saturn (in arc seconds) as seen from Earth when the two planets are farthest apart? arc secondsSome astronomers argue that Jupiter and Saturn areunusual, while other astronomers argue that all solarsystems should contain one or two such giant planets.
- What is the frost line in the solar nebula? Explain how temperature differences led to the formation of two distinct types of planets.The innermost rings of Saturn orbit in a circle with a radius of 67,000 km at a speed of 23.8 km/s. Use the orbital velocity law to compute the mass contained within the orbit of those rings.What is an exoplanet? Group of answer choices A planet in our solar system beyond Pluto. Any planet with extra-terrestrial life. A planet in an extra-solar star system outside of our solar system. Objects in the solar system such as Pluto that were once considered planets but no longer are.

[select all that apply] options: There would be more comets. Life would have been very unlikely to evolve here. There would be no comets. There would be fewer asteroids. There would be more asteroids. Jovian planets would have formed closer to Sun. Terrestrial planets would be large2. The destructive "Tunguska Event" of 1908 seems to have been due to an airburst by a modest-sized asteroid a direct impact on land by a large asteroid an ocean impact by a comet a nearby supernova explosion Astronomers have determined that the probability of a significant asteroid impact on Earth during your lifetime is about the same as the probabilty that you'll win the lottery.
