Each planet file has its own torrent. A new planet file means using a
new torrent to download it.
To simplify downloading the lastest planet, you'll find a
planet-latest.pbf.torrent similar to the planet-latest.pbf (it's a
symlink to the last planet available).
If you want to automate downloading new planet thru torrents, for
example to seed them, there's a rss.xml file you can use. Many
bittorrent clients support RSS to automate downloads.
