Based on current estimates, there are between 200 - 400 billion stars in our galaxy (The Milky Way). There are possibly 100 billion galaxies in the Universe. So taking the average of our galaxy, gives approximately 3 x 1024 stars. So about 3 septillion. This has been equated to the same number of grains of sand that are on Earth.

One source (BBC) stated that there are about 1,000 stars to every grain of sand on Earth!! There are an estimated 100 to 200 billion galaxies.

So taking a conservative number of 100 billion stars per galaxy gives an approximate total of 10,000,000,000,000,000,000,000 stars. (Which is 10 sextillion)

The newest estimates gained by the Hubble space telescope places the estimate of 500 billion Galaxies each with about 300 billion stars for each galaxy.
