Earlier this year, SpaceX founder Elon Musk and singer Grimes welcomed a new son. Following the announcement, the Tesla CEO and "Oblivion" singer revealed that they had decided to name him X Æ A-12 Musk. However, the unique name created an unexpected hurdle for the couple due to specific characters. As a result, the two had to make a compromise in order to make their son's name official.

According to TMZ, Elon and Grimes, whose real name is Claire Boucher, had to amend several components in order for it to be legally recognized by the state of California. As a result, they ended up naming him X AE A-XII Musk.

The previous issues arose when it came to including Æ and 12 in the name. As stated by TMZ, birth names in California "must be limited to the English alphabet," which means they cannot include numbers or special signs.

Prior to the problem being resolved, David Glass, a family law attorney, elaborated on what would have happened had they submitted their first choice.

"In California, you can only use the '26 characters' of the English language in your baby name. Thus, you can't have numbers, Roman numerals, accents, umlauts or other symbols or emojis. Although an apostrophe, for a name like 'O'Connor,' is acceptable," he stated.

Continuing, he added that the first name on the birth certificate likely would have been rejected after submission and they would have been asked to make changes. Had they fought the first decision, Glass also stated that they could have appealed the rejection, but doing so seemingly would have resulted in the same outcome.

Aside from the arrival of his new son, Musk has continued to stay in the news for other reasons as well. In recent weeks, SpaceX teamed up with NASA to send two astronauts, Bob Behnken and Douglas G. Hurley, to the International Space Station. According to Space.com, as the SpaceX Falcon 9 rocket launched the Crew Dragon Demo-2 mission to the ISS, a record number of people tuned in to watch it happen live. This, in turn, helped it become NASA's most-watched online event.
