Dr Maggie Aderin-Pocock: 'Dyslexia is misunderstood in lots of ways'
Doctor Maggie Aderin-Pocock is one of the UK's leading space scientists and has written more than 20 books about our solar system and beyond.
She was recently awarded the Royal Society Young People's Book Prize for her latest book, Am I Made of Stardust?, but Maggie says she finds it hard to take herself seriously as an author because she is dyslexic.
Dyslexia is a learning difficulty that affects about one in 10 people in the UK.
If somebody has dyslexia, they might have difficulties with their reading, writing or spelling.
It doesn't affect intelligence and it is not a disease or an illness - it is a condition that someone is born with.
We sent Newsround viewer Fraser, who also has dyslexia, to meet Maggie.
