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.

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...

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....

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...

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

a) At what distance from a 2 solar mass neutron star would a
planet like the Earth be tidally disrupted (that is, literally
pulled apart)? That is, how close would the planet need to be to
the NS for the difference between the NS’s gravity at the center of
the planet and at the surface of the planet to be greater than the
gravity holding the planet together?
b) Would the asteroid Pallas be able to get any closer? (Pallas...
