Which of the following condition will be true for a planet to have atmosphere?
[A] velocity of molecules in its atmosphere is lesser than escape velocity
[B] velocity of molecules in its atmosphere is greater than escape velocity
[C] velocity of molecules in its atmosphere is twice the escape velocity
[D] velocity of molecules in its atmosphere is equal to the escape velocity
We think the terrestrial planets formed around solid “seeds” that later grew over time through the accretion of rocks and metals.
a) Suppose the Earth grew to its present size in 1 million years through the accretion of particles averaging 100 grams each. On average, how many particles did the Earth capture per second, given that the mass of the Earth is = 5.972 × 10 ^24 kg ?
b) If you stood on Earth during its formation and watched a region covering 100 m^2, how many impacts would you expect to see in one hour. Use the impact rate you calculated in part a. You’ll need the following as well: the radius of the Earth is = 6.371 × 10 ^6 m and the surface area of the Earth is 4??^2Earth
Imagine that astronomers have just discovered a planet orbiting another star (other than the Sun), and they have reported the mass of the planet as 4.2 Jupiter-masses. Explain in a few words what this means.

- Look at Figure 21-11. Which molecule(s) can escape from Earths gravity? From Mars? From Venus? Figure 21-11 Loss of atmospheric gases. Dots represent the escape velocity and temperature of various Solar System bodies. The lines represent the typical highest velocities of molecules of various masses. The Jovian planets have high escape velocities and can hold onto even the lowest-mass molecules. Mars can hold only the more massive molecules, and the Moon has such a low escape velocity that even massive molecules can escape.arrow_forwardWhat is the escape velocity is km/s from Jupiters exosphere, which begins about 993 km above the surface ?

- What is the range of density for the outer planets (in g/cm3)? 1.2 to 5.5 2.2 to 5.5 2.2 to 6.5 3.3 to 7.2 none of thesearrow_forwardWhy do we think that planets in our Solar System were not formed out of the gaseous disk by direct gravitational collapse? Planets are formed in disks. Disks rotate too fast to collapse gravitationally to form planets. In disks that are not massive enough, tidal gravity of the central star prevents the disk gas from collapsing. The material in the disk orbits close to the star. This makes the disk too hot, and pressure support prevented the disk from gravitational collapse. The gravity of the forming planets was not enough to accrete gas.arrow_forwardIn the classic 1913 science-fiction novel At the Earth’s Core, by Edgar Rice Burroughs, explorers discover that the earth is a hollow sphere and that an entire civilization lives on the inside of the sphere.

- You decide to go on an interstellar mission to explore some of the newly discovered extrasolar planets orbiting the star ROTOR. Your spacecraft arrives in the new system, in which there are five planets. ROTOR is identical to the Sun (in terms of its size, mass, age and composition).
