The Grand Orbital Observatory of Coruscant was a building constructed for the purpose of observing celestial events. It was named similarly to the Core Worlds world Coruscant. Throughout the Republic Era, it was a common destination for members of the Jedi Order, notably the Jedi Padawan Jape as he learned about astrophysics from his Master. In 40 BBY, Jape informed his fellow Padawan Obi-Wan Kenobi of his trips to the observatory, which caused envy in his friend.
The Grand Orbital Observatory of Coruscant appeared in Master & Apprentice, a 2019 book penned by Claudia Gray.
