How to calculate the max mass and speed of an asteroid capturable by gravity assist?

After reading this question and the answers, I am wondering about the limits of slingshot method to capture an asteroid into a planet orbit. Is it possible to calculate if an asteroid can be captured ...

When doing an interplanetary Hohmann transfer, are additional escape and capture burns necessary in addition to the two Hohmann Transfer burns?

When doing a Hohmann transfer, it takes a burn to change from a low orbit to the Hohmann Transfer Orbit (HTO), and a second burn to change from the HTO to a high orbit. I know how to find the delta-v ...

How to estimate the pose of a dynamic cooperative and known object in space e.g in case of space debris? [closed]

I would like to know some novel approach, method or algorithm. The main purpose of pose estimation is to deal with the robotic capture in space

Has lithocapture ever been seriously considered as a method of entering orbit around a planet or moon that lacks any atmosphere?

What I mean by lithocapture is an orbital transfer maneuver used to reduce the velocity of a spacecraft from a hyperbolic trajectory to an elliptical orbit around the targeted celestial body where the ...

Why are most of Jupiter's moons retrograde?

Jupiter's small moons are likely captured objects. I would've expected half of them to be captured in retrograde orbit, between 90 and 180 degrees inclination. But out of 65 lesser satellites, only 11 ...

Calculating low-thrust capture delta-V with high $V_{inf}$

I'm designing a CubeSat mission to the Martian moons, and am having trouble calculating capture delta-V. Once it gets into a circular orbit, I can do the rest, but the capture itself is giving me ...

Why does a gravity capture require a loss of velocity?

I've read a gravity capture of an object requires the captured object to lose velocity by some means (impact, third body tidal force, etc). Is there not a possible encounter that happens at a low ...
