To complete the island, you must beat all three planets (jungle, ice, and fire). Each has its own "boss character" that can be defeated using one of the three Mystical weapons, usually provided by a helpful Space Knight :
Ice Planet - Sir Gawain gives you the Force Shield - defeat the Tiger Copter
Fire Planet - Sir Peleas gives you the Ice Arrow - defeat the Dragon
Jungle Planet - find the Laser Lance on the jungle floor - defeat the Mother Phoenix
(see related questions for full solutions)
(See the related questions for each of the three planets, and for the final battle on Mordred's asteroid.)
There are robot creatures on Astro Knights island, and you use the Mystical Weapons of Arturus to defeat them on the three planets.
When you have all three knights with you, they suggest you look for a giant asteroid, which happens to be at X-11 Y-82 in the Asteroid Belt.
all you get is the island medallion and 100 credits
Find the mystical weapon and the space knight, and beat the boss monster of each planet. On the jungle planet, you need to find the Laser Lance. On the other two planets, the knights provide the weapons. (see related questions)
You can play the three planets (jungle, ice , and fire) an any order. The Jungle Planet is the easiest, followed by Ice, then Fire. You must beat all three to complete the island.

As you defeat the three planets (jungle, ice, fire), the knights come along with you. So you have to beat all three planets to get all three knights. When you have them, go to the giant asteroid in the asteroid belt, near X-11 Y-84.
You still have to beat the other two planets (fire and jungle) before you can rescue the Princess. When you have all three space knights with you, you can go to the giant asteroid (X-11 Y-84) and pull out the Golden Key.
