Details
The Small Magellanic Cloud is a nearby dwarf galaxy and one of the Milky Way’s closest galactic companions. Its distorted shape records repeated tidal encounters with the Large Magellanic Cloud and the Milky Way.
The Small Magellanic Cloud is a gas-rich dwarf galaxy about 200,000 light-years away. Its irregular shape and extended streams of gas reflect repeated gravitational interaction with the Large Magellanic Cloud and the Milky Way.
Its lower abundance of heavy elements than the Milky Way provides a nearby environment for studying star formation under different chemical conditions. The quoted diameter describes its main visible body; its gas and stellar outskirts extend less regularly.

About
Scale of Space is a scroll-based journey through the universe, placing objects on a single logarithmic scale so you can compare size across an unbroken range.
Guides explain selected parts of that range, while focused views filter the objects by subject.
