Hohmann transfer problem

    1. The problem statement, all variables and given/known data

    You plan to visit the asteroid#1 (2.36 AU) and then asteriod#2 (2.77 AU). Assuming both asteroids are in the ecliptic plane, how much time(in years) would it take by hohmann transfer orbit to travel from earth to asteroid#1 on the first leg of your mission?

    2. Relevant equations

    I am not sure of the equations that would be needed for this type of equation.
    1AU=9.296x10^7 miles

    3. The attempt at a solution

    1AU=9.296x10^7 miles
    Asteriod#1 is 2.194x10^8 miles away from earth.
    This is all the information i have. I feel like i am short information...but i might not be....idk

    None of those help me with a time factor though.....

    is there a time substitute in here somewhere? do i compare au to a light year and go from there?

    What time factor?

    What is the nature of trajectory from Earth to the asteroid?

    the question asks how long will it take for this hohmann transferto take......which is the jump from the earths orbit to the asteroid

    You missed the second question. What is the nature of the trajectory from the Earth to the asteroid? What does the fact that this is a Hohmann transfer imply with regard to this trajectory?

    You will need some other information to solve this problem. There are some constants, most likely spelled out in your text, that you will need.
