No QPQ neccesary, this is my second DYK nomination and would prefer to watch and learn a bit more before reviewing others.

Also, it may be worth holding this one to go with a bunch of space themed DYKs in July. @Coffeeandcrumbs:? --Spacepine (talk) 11:29, 10 June 2019 (UTC)

I will make sure that happens once Bejinhan gives the green tick. --- Coffeeandcrumbs 11:42, 10 June 2019 (UTC)

Hi, I came by to promote this, but I don't see anything about satellites moving in a figure 8; the lead seems to be saying they don't move, but loiter. Yoninah (talk) 21:39, 14 July 2019 (UTC)

Third sentence says "The ground track of a satellite in a Tundra orbit is a closed figure 8"... They spend more time in one hemsphere, and overall motion is fig-8. Both things are true. Spacepine (talk) 00:11, 15 July 2019 (UTC)

OK, thanks. Restoring tick per Bejinhan's review. Yoninah (talk) 20:25, 15 July 2019 (UTC)
