SQL database: solar_system_objects

Hello!

I'm completing one of SQL challenges: Big Data Dig. I chose solar system objects and decided to create a table of  solar objects that can be considered habitable based on their size.   I  filtered the information from the database to find  solar objects in the so-called Habitable or "Goldilocks’’ Zone.

I'm wondering what other approaches Khan Academy users took to complete this challenge. Thank you!
