This is a picture of Mira out of the Hubble Space Telescope.

Mira is a binary star system with a white dwarf (Mira B, also known as VZ Ceti) star and a red giant (Mira A). Scientists think Mira is 200-400 light years away in the constellation Cetus. Mira is known to change size over time. Other red giant stars that do the same are called Mira variables.

Size

Mira has a diameter 332 to 541 times that of our sun.

If Mira did not change size, its diameter would be only 240 times larger than the Sun.
