Asteroid Trajectory Calculation via MATLAB

I’m currently trying to work on a code to calculate trajectories for rapid response missions to NEO’s. (Preferably from a parked earth orbit to a “moving” NEO) I want the code to consider NEO characteristics, orbital mechanics & collision detection. As well as show some sort of diagram to “view” the trajectory calculated.
Basically need it to calculate the trajectory view, delta V, time to collision, impact point, risk level and any other necessary value you can think of
It also needs to include the following:
- NEO classification criteria ( into high, moderate and low risk based on size, speed)
- Impact energy thresholds
- Easy to input parameters
I currently have a few files of code that I can send that it sort of needs to be based on



Key points code needs to include

Works so that Asteroid coordinated can be inputted into the code and it calculates the trajectory from a parked orbit within the sphere of influence (that coordinates can also be inputted)
- 2 body approximations (main =sun)
- trajectory calculations and plotting
- Coordinates
- Lambert targeting method
- Determining whether to deflect from a distance or closer (based off NEO risk)
- Delta V
- Thrust requirements
- Impact point
- Impact angle
- Velocity
- Asteroid classification (low, medium and moderate risk) based on size. Speed etc. (this will all be inputted. No need to calculate)
- Trajectory angle
- Approach angle
- Are we able to stop the “deflection mission” midway through and recalculate? I.e. changing the time to impact and approach angle if necessary - correcting trajectory errors
- Direct impact not slingshotted!
