M2J-463

M2J-463 is a planet in the Pegasus galaxy, which has a Stargate.

In 2009, the planet was invaded by the Unknown Aliens.

A couple of the planet's natives watched as the aliens were disintegrated through a beam of light that erupted from their planet's Stargate, which was caused by Dr. Rodney McKay, who used the McKay/Zelenka Attero device on the Stargate Network, targeting the Alien's energy signature from their subspace domain,and disintegrated all traces of the Aliens.
