The time of opposition can occur as much as 8.5 days away from the closest approach. The distance at close approach varies between about 54 and about 103 million km due to the planets' elliptical orbits, which causes comparable variation in angular size.
Cosmos often simply means universe. But the word is generally used to suggest an orderly or harmonious universe, as it was originally used by Pythagoras in the 6th century B.C. Thus, a religious mystic may help put us in touch with the cosmos, and so may a physicist.
The unit name, Cosmos, is a term referring to the universe as a whole and alludes to Ichigo and Akari's surnames, with the Hoshi (æ,) from Hoshimiya and the zora (ç©º, sora) from Åzora combined to form Hoshizora (æç©º,), meaning starry skies. The unit name also has a double meaning, referring to the cosmos flower. This motif can be seen in the music video for Floor of the Starry Sky, as well as the special Cosmos Photokatsu! phone wallpaper. Despite being present in the anime, Cosmos' unit name was only first revealed in Aikatsu! Photo on Stage!!.
