Very difficult, insightful, challenging and interesting course! Worth all the time spent, gain a lot of new knowledge. Thanks professor for this course.

A worthy course for knowing the Solar system, of easy understanding, which make me think about the bright design it has. No better way.

Thanks, profesor.

Excellent course with a great lecturer and guest lecturers. Interesting stuff about our solar system and the ways we explore it. Highly recommended!

Amazing course! Much, much better than the other Caltech astronomy course, and right up there with the fantastic ANU Astrophysics courses on edX.

Excellent course and instruction. I would highly recommend this challenging course to anyone wanting a solid science update on our solar system.

One of the best coursera courses ever !!!. probably a bit difficult for the novice, but very good for anyone with some basic science background.

Excellent course. Very informative and conceptually enlightening. Professor Mike Brown is one of the best teachers I have ever studied under.

Excellently taught. I was able to understand almost everything despite only being 14 and not knowing most of the physics involved beforehand.

Loved every minute of it, could not do some of the maths, that otherwise very informative.

Like Mike Brown's technique… Enjoy the humour!

Absolutely fantastic course. It's both broad and rigorous and uses the appropriate math and chemistry to show how we know what we know.

Professor Mike Brown is awesome. He does not let any student distract. He has a unique teaching charm for which I appreciate him a lot.

This is an amazing course.Thank you Dr Brown for allowing me to pursue this course from the comforts of my home.And thank you coursera.

It's quite interesting course for geoscientist in a sense to observe the activities that happens in the solar system over the decade.

The professor is really chill and also very passionate about his research. Would recommend to anyone interested in our solar system.

good course , instructor was very informative , clearly presented. The information presented in this course needs to be updated .

Mike Brown is one GREAT professor. His tests are designed to make one think really har siinc the correct answers are not obvious.

Very interesting and well taught. Not too complicated while still not being too general. Some things seem outdated though.

Thank you, Prof. Mike Brown & Team for this Course, It's look like this course make us to explore in the solar system. :)

Big thanks for Caltech and Staff, specially to Mr Mike Brown for making me literate in Astronomy.

Best wishes to you all.

Amazing course! I found the art of teaching of Prof. Mike Brown absolut fantastic! one of the best courses on coursera!

The course taught me a lot, and was perfectly balanced between being informative and technical. Highly recommended.

Way over my head but has definitely given me a reason to pursue learning more about physics and the solar system.

I love this course. Everything is very detailed but it's very hard to understand. But still manage to finish it!

Me encantó porque se dio una explicación muy detallada de cada tema. Espero recibir actualizaciones. ¡Gracias!
