Did the Chicxulub asteroid have any impact on Earth's orbit?

Well, obviously it had *some* impact: it was just extremely small.

The Earth relative to the Sun has a kinetic energy on the order of 10^33 joules. The impact had an energy around 10^23 joules, and not all of this went towards altering the Earth's orbit either.

On a practical scale, there simply wasn't any kind of significant difference before and after the impact. It's like adding a couple centimeters to the Earth-Moon distance and expecting it to look different now.
