From the project home page:

Planet is a flexible feed aggregator. It downloads news feeds published by web sites and aggregates their content together into a single combined feed, latest news first. It uses Mark Pilgrim's Universal Feed Parser to read from CDF, RDF, RSS and Atom feeds; Leonard Richardson's Beautiful Soup to correct markup issues; and either Tomas Styblo's templating engine or Daniel Viellard's implementation of XSLT to output static files in any format you can dream up.

You can use this tool to combine two or more feeds easily i.e. this software act as a "Feed Aggregator".
