Fact check: Does Elon Musk have any sisters and what are their names?

1. Summary of the results

Elon Musk has one confirmed full sister, Tosca Musk, who is a filmmaker and entrepreneur, known for co-founding Passionflix ^{[1] [2]}. He also has two half-sisters, Alexandra and Asha Rose, from his father Errol Musk's marriage to Heide Bezuidenhout ^{[1] [3]}.

2. Missing context/alternative viewpoints

• Tosca Musk was born on July 20, 1974, and has established herself as a South African filmmaker ^[1]
• The family structure is more complex than simply listing siblings, as it involves half-siblings from his father's subsequent marriage ^[3]
• Tosca has achieved notable success in her own right as an entrepreneur, specifically in the entertainment industry with her streaming service Passionflix ^{[1] [2]}

3. Potential misinformation/bias in the original statement

• There is some conflicting information in the sources:
• One source incorrectly identifies Kimbal Musk as a sister, when he is actually Elon's brother ^[1]
• Some sources mention only Tosca ^[2], while others provide a more complete picture including half-sisters ^[3]
• The simple question about sisters overlooks the complex family dynamics of the Musk family, including:
• The distinction between full siblings and half-siblings
• The relationship through Errol Musk's subsequent marriage
