Kepler-1625b is the name of a planet found outside our
solar system. Its mass is 3180x larger than Earth and its radius is
9x larger than Earth
(a) What is the gravitational acceleration (little g) on the
surface of this planet?
(b) This planet may have a moon. If it has the same mass of Earth
what is the gravitational force between the planet and moon? If the
moon orbits 400,000 km away how fast does it orbit?
Solutions
Expert Solution
The basic idea behind solving this question deals with the equations involving the laws of gravitation.
1. Force between two objects of different masses placed at distance 'r' .
2. Gravitational field strength.
Every required notation and formula with solution is given in the following images
There fore
For the part a) the solution is the gravitational acceleration is 31212 m/s^2
And for the part b). The solution is the force of attraction is 47,247.80 * 10^21 Newtons and the subpart of Orbital velocity is 56264 m/s^2.
Thank you !!!!

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...

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...

Problem 4. Consider a simple solar system that contains one star
(mass M) and one planet (mass m) in a circular orbit with radius r.
The planet orbits at speed v. (v can be computed in terms of G, M,
m, and r using Kepler’s 3rd Law and/or Newton’s Law of
Gravitation.) Due to conservation of momentum, as the planet
changes its velocity vector, the star’s velocity vector will also
change. Astronomers can detect a star’s changing velocity from its...

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...

Description: Our solar system is very diverse when it comes to
the gas composition on our planets. On Mercury, which has almost no
atmosphere, the pressure is less than 10-14 bar. Venus on the other
hand has a much more dense atmosphere than earth, with a pressure
of 92 bar. Instructions: Write a response to the following prompt
and then respond to your peers.
Would having different atmospheric pressures have an effect on
the accuracy of gas laws? If so,...
