There are several reported types of UFO’s (Unidentified Flying Objects) including:

1. Saucer-shaped: the classic flying saucer shape, often depicted in popular culture.

2. Sphere-shaped: spherical or circular objects that have been reported in sightings.

3. Triangle-shaped: triangular objects that have been reported in sightings, sometimes with lights at each corner.

4. Cigar-shaped: elongated objects, sometimes with lights or windows, that have been reported in sightings.

5. Disk-shaped: flat, disk-like objects that have been reported in sightings.

6. Boomerang-shaped: objects shaped like a boomerang that have been reported in sightings.

It’s important to note that many UFO sightings remain unidentified and it is possible that some UFO sightings could be misidentified aircraft, weather phenomena, or other natural or man-made objects. The existence of extraterrestrial life and UFO’s is still a topic of speculation and investigation.
