There's a Conan ending called Aoi Aoi Kono Hoshi Ni by Azumi Uehara
However, it's listed as "Aoi Aoi Kono Chikyuu ni"
Here's a reference ..
Another reference:Aoi Aoi Kono Hoshi ni is Uehara Azumi's debut single. The title track was used as the 13th ending theme for the anime Meitantei Conan. The lyrics for both original songs on the single were by Uehara herself, with addition help from AZUKI Nana on the title track.
It is often incorrectly romanized as "Aoi Aoi Kono Chikyuu ni" due to the characters used.
The reason this bothered me is because I searched for it on AnimeLyrics.com but didn't find anything! I had to go to Detective Conan's page to look for it.『青い青いこの地球に』（あおいあおいこのほしに）
