Little Planet Soyuz
Explanation: Engines blazing, a large rocket bids farewell to this little planet. Of course, the little planet is really planet Earth and the large rocket is a
Soyuz-FG rocket. Launched from the
Baikonur Cosmodrome in Kazakhstan on June 6 it carried a Soyuz MS-09 spacecraft into orbit. On board were
International Space Station Expedition 56-57 crew members Sergey Prokopyev of Roscosmos, Serena Aunon-Chancellor of NASA and Alexander Gerst of ESA. Their spacecraft successfully docked with humanity's orbiting outpost just two days later. The little planet projection is the
digitally warped and stitched mosaic of images covering 360 by 180 degrees, captured during the 2018
Star Trek car expedition.

That's a very big rocket to overcome the puny gravity of that little boulder of a planet.
But perhaps the planet isn't a planet, but a white dwarf? Or a neutron star? Sorry, proud rocket. I don't know what kind of engines you'd need to take off from a neutron star, but in any case, you wouldn't stand so tall!
(But I can see what looks like grass and bushes growing on the little planet... I didn't think that kind of stuff would grow on a neutron star...)

This APOD reminds me of a song that was on Disney, perhaps the Mickey Mouse Club, that went something like; "It's a small world after all, it's a small, small world."

If it were a neutron star, intense gravity would crush the metal in a thin layer over the surface

Why did it take two days to reach ISS? And why does the caption say "just" two days?

It would be nice if we could get back to ASTRONOMY pictures on ASTRONOMY Picture Of the Day ! I'm tired of weather (cloudbow) pictures and heavily photoshopped rockets (today). There are billions of actual astronomical objects of which to post pictures.

If the Earth were crushed to a diameter of ~80 m (almost white dwarf density)
it would have an escape velocity of ~0.015 c.

"On board were International Space Station Expedition 56-57 crew members Sergey Prokopyev...." Didn't he write the music, Peter and the Rocket?
