Orbits stability:?

Question

Can three stars with the same mass stay forever in a circular (located at 120 degrees) orbit around the barycenter (center of the equilateral triangle),?
What about 4 stars at 90 deg? or 5,6...stars?

If two identical stars be in a near circular orbit, can exist a planet in a orbit like a "8" around those stars?. What if we have 3 stars as the first question: Would be the planet move in a stable orbit like a trifolium?

Can three stars with the same mass stay forever in a circular (located at 120 degrees) orbit around the barycenter (center of the equilateral triangle),? (I know that 120 deg in the same orbit of the Moon exist a stables points).
What about 4 stars at 90 deg? or 5,6...stars?

If two identical stars be in a near circular orbit, can exist a planet in a orbit like a "8" around those stars?. (remember the Apollo trayectory)
What if we have 3 stars as the first question: Would be the planet move in a stable orbit like a trifolium?

Answer 1

Not forever. They will eventually be brought into the center of gravity and collide with each other. The stars' gravity would disturb the orbits to the point to where they could not exist like that (3 stars+).

The planet would orbit around the center of gravity that the stars are orbiting around. So it would just have a circular orbit outside of the star orbits (its orbit would also be disturbed by the gravity of the stars). Once the orbit was disturbed, the planet would either get sucked into one of the stars (due to the gravity putting the planet in the path of one of the stars) or would be sucked closer to the center of gravity and the stars would orbit around the planet...i think. i read up on this kind of thing before, but am a little rusty.

Try to do some research on the subject. i doubt you will get a 100% correct answer on Y! Answers.

Hope I was of some assistance, though.

Answer 2

The circular orbits with equaly spaced stars aren't stable. For three stars you can have them chasing each other round in a figure 8, but I don't know if it's stable for more than three.

Figure 8 planetary orbits around a binary star aren't stable either.

Answer 3

We vehicle owners force our vehicles around. at last they choose an alignment. We take them in and have them aligned, confident? We shelter the alignment of our vehicles. on your question, you have allowed for the certainty that God created the moon, which, in accordance to scientists, provides to earth's stability. very nicely. Is it not lifelike to have faith that if God made the moon and placed it the place it is, he may additionally shelter its orbit? If we comprise God interior the equation of putting the moon there interior the 1st place, why exclude him from the equation while it consists of protecting it? isn't it lifelike to have faith that for the time of time, if and while needed, he will do a direction correction, because it have been? do not we do wheel alignments, as above? At interest 38:33 we examine: ""do you comprehend the ordinances of the heavens, or restoration their rule over the earth?" New American established. The heavens comprise all celestial bodies. The Hebrew be conscious here rendered "ordinances" consists of the thought-approximately statute, something prescribed. The Hebrew be conscious here rendered "restoration" consists of the thought-approximately to set, place, rent. And the Hebrew be conscious here rendered "rule" consists of the thought-approximately authority. inspite of their present day kit and stepped forward mathematical understanding, astronomers are nonetheless unable to absolutely understand those statutes put in place via God. So, the divinely appointed statutes of the heavens administration all celestial bodies. And God controls the divinely appointed statutes. Hannah J Paul

Answer 4

There's no reason why they can't. In fact there are globular clusters with 100,000 of stars with stable but random orbits that survive,

Answer 5

Three stars can and do orbit each other, but probably not in the configuration that you describe.
