No. That's wrong. A single molecule would be one H - hydrogen and two O - oxygen.

That's not

That's not what's in a water molecule

The molecule you describe would be absurdly reactive, I sure as hell wouldn't drink it

#someone explain this to me like im stupid#I thought one molecule of water is just like#H2O

One molecule of water has 2 hydrogens

The solar system has one star

The statement is correct

The joke is that "there are more molecules in a single glass of water than stars in the galaxy" is a common thing to say. So the reader immediately sees "hydrogens in a single molecule of water" and assumes that the writer of the statement has made a mistake. It can take a few readings before noticing that the writer said "stars in the solar system" and not the expected "galaxy", the writer was correct all along, it is us who is the fool. Such fun.

Do you... get a lot of use out of this tag?

Is... is the sun... the only star in this solar system? Aren't there other smaller stars? Or maybe the sun is just the nearest one? All the stars in the night sky are not in our solar system?

Galaxy:

(This galaxy is Andromeda, we can't get a great perspective shot of ours because we're inside it, but you get the idea.)

The solar system has one star (Sol, our sun.) The stars you see at night have their own solar systems. They're the other stars in our galaxy. So isn't very big, as stars go, so a lot of those stars are not smaller than ours. Just far away.

As a side note to avoid confusing people, yes, many solar systems have 2 stars. Ours does not.

Crazy to think is the orbit of the earth around the sun and how it's not level.

Official nature post

The Earth actually does orbit on a very level plane, called the ecliptic. (All of the planets orbit on that same level plane!) This effect has to do with the tilt of the Earth's axis instead! That, combined with our rotation, has a much greater effect on our view of the sky than our orbit around the sun does. The tilt is also the same thing that creates the seasons; it's a similar principle, coming back to the question of which parts of the planet get to be facing the sun at different times of the day and the year.

There is a short-and-sweet breakdown here, a more detailed explanation with some history of how various people figured that out here, and more on the Earth's tilt and the seasons here. Check them out!

…and to further complicate motion, if you were watching from another solar system you’d see the Sun wiggling from gravitational effects, too, and changing course while passing other stars and also spiraling around the Milky Way Galaxy at 828,000 km/hour in its 230 million year orbit

Why is this heat so hot 😩

It’s the heat

The clearest picture of the sun ever recorded!

The Sun is not made of fire, its energy comes from nuclear fusion to its heart, where the temperature exceeds 15 million degrees and the pressure is immense. It melts hydrogen atoms, turning them into helium, releasing energy in the form of light and heat in the process.

Every second, it converts 600 million tonnes of hydrogen into 596 million tonnes of helium, the 4 million tonnes of missing matter is converted into energy - a process that will continue for the next 5 billion years.
