Who givers the energy to planets to float in space?

Question

Please dont answer gravitations energy as it is ony an explaination not the answer!!!!!!!!

Answer 1

space is not a fluid that planets need to float in it is just plain emptiness.

Answer 2

"It is dimmer than all but three known globular clusters," explained colleague Michael Blanton, also of NYU. "Moreover, these dim globular clusters are all much more compact than Willman 1. If it's a globular cluster, it is probably being torn to shreds by the gravitational tides of the Milky Way."

A dark possibility

There might be a way to figure out what to call the thing.

If it is a galaxy, then it ought to contain a bunch of dark matter, mysterious stuff that can't be seen but that contributes more mass to galaxies than the collective heft of stars, gas, planets and dust. Problem is, nobody knows how to detect dark matter directly. It's only suspected because without it, galaxies don't have enough mass to hold together as they do.

Scientists want to know what dark matter is made of and what role it plays in the birth and development of galaxies. A first step, however, is to figure out exactly where the stuff hides.

Most astronomers think the Milky Way is surrounded by hundreds of clumps of dark matter, each of which might include a dim dwarf galaxy. Yet only 11 dwarf galaxies have been found around the Milky Way.

Perhaps, theorists speculate, some of the dwarfs contain very few stars and are just too hard to find with current technology. It follows that perhaps Willman 1 is an example of these.

"If this new object is in fact a dwarf galaxy, it may be the tip of the iceberg of a yet-unseen population of ultra-faint dwarf galaxies," Willman said.

Ambiguity reigns

Another possibility is that Willman 1 hints at all of the above.

"The colors of the stars in Willman 1 are similar to those in the Sagittarius tidal stream, a former dwarf companion galaxy to the Milky Way now in the process of merging into the main body of our galaxy," said Brian Yanny, an astrophysicist at the Department of Energy's Fermi National Accelerator Laboratory.

"If Willman 1 is a globular cluster," Yanny said, "then it may have piggybacked a ride into our galaxy's neighborhood on one of these dwarf companions, like a tiny mite riding in on a flea as it, in turn, latches onto a massive dog."

The ambiguity of the new object re-raises the question of whether some small fraction of things classified as globular clusters may be the stripped down remains of what used to be a dwarf galaxy," Willman said via email.

The finding was made with observations from the Sloan Digital Sky Survey.

More observations of the star cluster might allow researchers to figure out how to categorize it, which would allow a better understanding of how our Milky Way formed.

Answer 3

Newtons first law says
An object will continue to be in its state of motion unless acted by an external forces

Now since they are in motion they do not need any energy now it is just tht some point in the history they may have gained momentum but since there is no xternal force in space they are neither being accelerated nor decelerated but they are in constant state of motion

Answer 4

They don't float.

Space is almost completely empty and the planets just whizz through it on tranjectories determined by their momentum and the graviational forces of other bodies acting on them.

In the words of Monty Pythin:

Just remember that you're standing on a planet that's evolving
And revolving at nine thousand miles an hour.
It's orbiting at nineteen miles a second, so it's reckoned,
The sun that is the source of all our power.
Now the sun, and you and me, and all the stars that we can see,
Are moving at a million miles a day,
In the outer spiral arm, at fourteen thousand miles an hour,
Of a galaxy we call the Milky Way.

Our galaxy itself contains a hundred million stars;
It's a hundred thousand light-years side to side;
It bulges in the middle sixteen thousand light-years thick,
But out by us it's just three thousand light-years wide.
We're thirty thousand light-years from Galactic Central Point,
We go 'round every two hundred million years;
And our galaxy itself is one of millions of billions
In this amazing and expanding universe.

Answer 5

That's a very good question?

The hands that hung the stars and the heavens also wiped away the tears of the widow and the leper." - Max Lucado

Job 9:7
Which commandeth the sun, and it riseth not; and sealeth up the stars.

Psalm 8:3
When I consider thy heavens, the work of thy fingers, the moon and the stars, which thou hast ordained;

Psalm 147:4
He telleth the number of the stars; he calleth them all by their names.

Mankind can attempt to explain how these things work, but the bottom line will always be that only God can make it so.
