Miley Cyrus has no shortage of tattoos, and it seems the pop star is having trouble keeping up with her latest ink.

The singer shared a photo of a tiny planet she had tattooed on her arm. The problem? In the caption for the image she called the planet Jupiter, sharing the hashtag #lilbbjupiter. The planet in her tattoo, however, has very visible rings, which is a signature of Saturn. 
 

Some commenters noticed Cyrus' error and alerted her to the mistake. 

One simply wrote, "thats saturn." Others defended the star. 

One fought back on behalf of the star. "Why don't you buy a book about space. You need one considering this is Jupiter."
