Asteroid capture is an orbital insertion of an asteroid around a larger planetary body. When asteroids, small rocky bodies in space, are captured, they become natural satellites, specifically either a
Phoebe is an irregular moon of Saturn on a distant and highly inclined retrograde orbit, unlike the rest of Saturn's regular moons. Because of its unusual orbit, Phoebe is thought to be a minor planet from the outer Solar System that was captured by Saturn.
Asteroid grippers on the end of the robotic arms are used to grasp and secure a 6 m boulder from a large asteroid.

The 'Option A' was to deploy a container large enough to capture a free-flying asteroid up to 8 m (26 ft) in diameter.
In astronomy, an irregular moon, irregular satellite, or irregular natural satellite is a natural satellite following an orbit that is irregular in some or all of the following ways: distant; inclined

…around a larger planetary body. When asteroids, small rocky bodies in space, are captured, they become natural satellites, specifically either an irregular moon if permanently captured, or a temporary satellite. All asteroids entering Earth's orbit or atmosphere so far have been natural phenomena; however, U.S…
Irregular satellites of Jupiter (red), Saturn (green), Uranus (magenta) and Neptune (blue) (including Triton at the top left). The horizontal axis shows their distance from the planet (semi-major axis) expressed as a fraction of the planet's Hill sphere's radius. The vertical axis shows their orbital inclination. Points or circles represent their relative sizes. Data as of February 2024.
