At what orbital radius would a planet in our solar system have to be to enjoy “Earth-like” temperatures and conditions when the Sun arrives at the tip of its Red Giant “branch” (about 5 billion years hence). Compare your answer to the present orbital radius of Pluto. Assume that the orbit of earth is circular around the sun.

Life has been found on a newly discovered planet not too far from our solar system! The planet is named Nairb. A mission was sent to Nairb to learn more about these new life forms and the following data was obtained. The life forms on Nairb have a similar appearance to those of earth. These new life forms are also composed of many very similar molecular building blocks to life forms on earth, for example: amino acids and lipids are...

The orbital region of Earth is known as the Goldilocks region in our solar system where the probability of life to exist is higher than any other regions which may be too hot or too cold. My question: Why did we make such a wild assumption that, for life to exist we need a neither hot nor cold region or there has to be oxygen and water? There might be alien life which require say Plutonium or Mercury to live....

3) Consider a spherical planet in our solar system with radius, R, that behaves like a perfect blackbody, absorbing all of the sunlight hitting its surface and radiating light isotropically according to its temperature. At what range of distances from the Sun could this planet support liquid water on its surface? Hint: Solve for the equilibrium temperature of the planet where the light energy it absorbs equals the energy radiated away, and then find the distances where this temperature is...

5. The difference between a solar day on Earth and a sidereal day is about 4 minutes. If the Earth orbited the Sun at 0.5 AU, what would the difference be? (Assume the Earth’s orbit is circular and the rotation rate is the same.) Please explain clearly and provide explanations for how you solve this so I can learn. Thank you.

5. Other Solar Systems. Suppose we found a solar system with the properties described (note that these are not real discoveries!). In light of our theory of solar system formation, decide whether the discovery should be considered reasonable or surprising. Explain your answers. A. A solar system has four large jovian planets in its inner solar system and seven small planets made of rock and metal in its outer solar system. B. A solar system has five terrestrial planets in...

To study the Earth, some aliens have put a spaceprobe in the solar system. It has an elliptical orbit with a semi-major axis of 2 AU. The closest distance the probe gets to the Sun is 1 AU. a. What is the farthest the probe gets from the sun? b. What is the sidereal period of the probe (in years)? What is its synodic period? c. At what point will the probe be moving the slowest? The fastest? d. What...

Create an enumeration named Planet that holds the names for the eight planets in our solar system, starting with MERCURY equal to 1 and ending with NEPTUNE. Write a program named Planets that prompts the user for a numeric position, and display the name of the planet that is in the requested position. For example, if 3 is input, the output would be: EARTH is 3 planet(s) from the sun Answer in C# (Posting incomplete and probably wrong code that...

Snowball Earth: Mission to Planet Earth in the Distant Past In this class, we've learned about our planet, the Earth, and about many other planetary bodies in our solar system. We've seen that there are many interesting similarities and differences between them. The Earth resides in the warm inner solar system, near the Sun, but Venus and Mercury are even hotter than the Earth. Most of the solar system is farther from the Sun than the Earth is, so we've...
