- Its star catalog draws on Hipparcos, Yale, and Gliese data; the site says distance uncertainty can shift the light-travel date by weeks or months.
Field notes
The matching is based on measured stellar distances, not a star being named for the visitor. The site identifies Hipparcos, Yale, and Gliese among its catalog sources and notes that distance uncertainty can make the birthday-light match approximate by weeks or months. For birthdays before age four, it says the matching light has not reached Earth yet and gives the expected arrival date.
