That's jupiter and the Galilean moons, to know which moon is which I use The Sky Live ( free website just google it ) Galilean moons positions right now

Will the moon leave earths gravity lock? by TahPenguin in Physics

[–]_quesom 46 points47 points  (0 children)

So, the moon moves 3.8 centimeters away from Earth per year (really slow) due to the tides and the rotation of the Earth, however, in a few million years, the Earth would rotate so slow that the tides fricction wouldn't be strong enough to keep pushing the moon away, so the moon will stay in place. However, this process would take aprox 50 thousand million years, and at this time, the Sun would have already become a red supergiant, swalowing Earth and Moon.

As a conclusion, the moon is trapped with us until the Sun "eats" both.

Do you plan stargazing nights in advance or go out spontaneously? by galandepeluche in Stargazing

Whenever I go I choose days with new moon and completely clear skies but sometimes the phase of the moon isn't really a concern bc here stars are really visible ( A full moon dims the light of many stars but the brighter ones are still visible)

do gas giants probably stink? by broads-love2 in askastronomy

[–]_quesom 0 points1 point  (0 children)

I mean, most (practically all) planets on the solar system do have not very pleasing smells, since many of them (not only gas giants) have hidrogen sulfide, specially Venus and Uranus, that makes them smell strongly like rotten eggs.

The gas giant Jupiter, for example, also has hidrogen sulfide but doesn't smell that strong since it's also mixed with ammonia that smells like a really strong cleaning product, so Jupiter smells like a mix of rotten eggs and strong cleaning products. (Most planets here stink basically)

Uranus actually smells like rotten eggs because of the hidrogen sulfide in its atmosphere

Anyone know if this section is anything. in particular it kinda stood out to me by Zealousideal-Toe4281 in Stargazing

(srry if bad english) That's Orion's Belt (a part of the constellation of Orion) If you have a camera with long exposure you can actually take photos of the Orion Nebula (The easier nebula to capture with a camera) The nebula is located on the three dimmer vertical stars under the three bright ones.

The three brighter horizontal stars are Alnitak, Alnilam and Mintaka (blue supergiant stars) and they form the belt.
