What is the most stable orbit?
Explanation: Half-filled and fully filled orbitals are most stable.
What is stable orbit?
A stable orbit is one in which the satellite’s speed is just right – it will not move off into space or spiral into the Earth, but will travel around a fixed path.
What keeps the object in an orbit around the Earth?
Gravity is the force by which a planet or other body draws objects toward its center. The force of gravity keeps all of the planets in orbit around the sun.
How stable is the Earth’s orbit?
The Solar System is stable in human terms, and far beyond, given that it is unlikely any of the planets will collide with each other or be ejected from the system in the next few billion years, and the Earth’s orbit will be relatively stable. …
Which has the most stable electronic configuration?
The most stable electron configuration is that of a noble gas, due to the fact that its valence shell is filled. For helium, that means two valence electrons (a duet) in the 1s sublevel, and for the rest it means eight valence electrons (an octet) in the outermost s and p sublevels.
What is stable configuration?
Atomic Structure | Exercise (a) Stable electronic configuration means an atom in which the outermost (valence) shell is complete. Valency is the number of electrons lost or gained from the outer shell of the atom.
Why is Earth’s orbit stable?
Elliptical orbits are actually stable already. When the earth is farthest from the sun, its velocity is slowed enough that it does not escape. As the earth falls back toward the sun, it speeds up. By the time it reaches its closest approach, it is moving fast enough to avoid falling into the sun.
What keeps moon in orbit around Earth?
The Earth’s gravity keeps the Moon orbiting us. It keeps changing the direction of the Moon’s velocity.
How does the Earth stay afloat?
The answer is gravity and angular velocity – the gravitational pull of the Sun on the Earth keeps the Earth from flying away and the fact that the Earth has angular momentum keeps it rotating around and not falling in to the Sun. Imagine swinging a small weight on the end of a string in a circle.
Which configuration is stable?
Stable configuration Noble gases have stable configurations. Their valence shell is complete. They have two or eight electrons in their valence shell. They do not gain, lose or share electrons.
Is there such a thing as a stable orbit?
This isn’t a “stable” orbit by any means but it’s an example of an unstable but useful orbit for the life of a satellite. The James Webb Telescope, when it’s launched will orbit around Earth’s L2 Lagrange point, which isn’t stable, but it requires relatively small adjustments to stay in that order.
Is it possible to prolong an orbit via Moon power?
Our Moon, however, even though it’s slowly moving away from Earth, is sufficiently stable that it will outlast our sun. It’s stable on the scale of many billions of years. As to your question “prolong an orbit via moon power”, The moon tends to destabilize, not stabilize orbits around the Earth.
What is the difference between a stable and unstable planet?
There’s no neat and tidy definition between stable and unstable. Hubble for example, orbits the Earth every 97 minutes, and in a few years, primarily slowed by the very slight air resistance, it is expected to fall to the Earth.
How do satellites stay in orbit for so long?
Many satellites, because their equipment doesn’t last forever, are designed to gradually slow by air resistance and fall to the Earth after a few decades of operation. Satellites can be positioned where they stay in orbit much longer simply by moving them a bit further out, but there’s little benefit to that.
