# Highest velocity impact between a spacecraft and a solar system body? What about for a dedicated impactor (spacecraft component)?

In this answer I mention the proposed impact of DART:

DART's impact velocity would be about 6 km/s on a body so small that the momentum transfer is hoped to measurably change its orbit around a companion asteroid.

I wondered about impacts used for other reasons, so I'd like to ask:

1. What's the highest velocity impact between a spacecraft and a solar system body?

2. What about for a dedicated impactor (spacecraft component)?
