If you have Pokemon Heart gold you get the blue orb from mr. pokemon.I'm not sure if you can get the blue orb in Pokemon Soul silver
It is not possible to get a blue orb in Pokemon Soul Silver however, you can transfer Kyogre from Heart Gold to Soul Silver to get the green orb in order to catch Rayquaza.
You have to trade with silver to get, or blue and yellow.

Blue is the 16th gym leader in Pokemon Gold, Silver, HeartGold and SoulSilver versions. In Gold and Silver his team consists of Pidgeot; Alakazam; Rhydon; Gyarados; Exeggutor and Arcanine. In HeartGold and SoulSilver he uses the same Pokemon with slightly higher levels.
Blue uses all different types of Pokémon, so he doesn't really have a type given to him.

Yes you can trade Pokemon from Pokemon silver to Pokemon blue. The only restrictions on this is that you can not trade any of the new Pokemon that are introduced in the newer game (Pokemon with the number 151 and up can not be traded to Pokemon blue).
Blue is in Cinnabar Island. But to be able o fight him, you have to find Blaine, the gym leader. He is in the Seafoam Islands. Beat him and then talk to Blue again. H will then return to his gym.
