Character from Project Hail Mary by Andy Weir
The Russian astronomer who first saw the infrared thread between the Sun and Venus — and named the thing that was killing humanity's star before anyone knew what it was.
Petrova is the person who rang the alarm. She identified the Petrova line — the infrared arc between the Sun and Venus formed by migrating Astrophage — before anyone understood what Astrophage was. The phenomenon, the taskforce, and by extension the entire human response to the crisis bear her name. She is a scientist in the purest sense: she saw something anomalous, documented it, reported it, and let the implications unfold. She didn't need to save the world herself — she just needed to point at the sky and say 'that shouldn't be there.' The rest followed.
Russian academic — carries the quiet intensity of someone who spends long hours staring at data until patterns emerge that no one else sees.
Also known as: Petrova, Dr. Petrova
