When a planet moves around a star, it causes the star to wobble a bit from side to side as planets follow an elliptical orbit rather than a circular orbit. Astronomers can then use this fact to see whether stars have planets.

How do planets made entirely from gas keep from disapating?

Gas planets are able to hold onto their gas due to the strong gravitational forces pulling the gas particles towards the center of the planet. This gravitational force helps to keep the gas molecules together and prevent them from dissipating into space. Additionally, the immense pressure at the center of gas planets helps to keep the gas molecules compressed and bound to the planet.


Why do planets need their stars?

Planets need their stars for heat and light, which are essential for supporting life and maintaining stable surface temperatures. Additionally, the gravitational pull of the star helps to keep planets in orbit around it.


Why do earth and the moon remain in their orbits?

(simplified) Gravitational force of attraction is balanced by centripital force due to earths velocity. (G*m1*m2) / r2 = m2 * (v2 / r) m1 = sun mass m2 = earth mass r = earth - sun distance v = earths orbital velocity G = newtons gravitational constant

Are dwarf planets and minor planets the samet hing?

Dwarf planets are celestial bodies that have enough mass to have a gravitational pull by the sun, but they are not large enough to be considered a regular planet. They are also too big to be satellites. Minor planets are in direct orbit with the sun. They are not dominant planets, and they are not comets. This qualifies all dwarf planets as minor planets. So, to answer your question, not exactly. All dwarf planets are minor planets. But not all minor planets are dwarf planets. Hope this helps you!!

How do planets affect us?

Planets do not have a direct impact on individuals as astrology suggests. Planets in the solar system affect Earth's environment through gravitational forces and orbits but not human behavior or events. The study of planets helps us understand our place in the universe and the conditions necessary for life.


A specific answer on why planets and moons of planets stay in their orbits?

Planets and moons remain in their orbits because of the gravitational pull other bigger planets or stars have on them, for example the Earth stays in its orbit because of the gravitational force it is subjects to created by the Sun, and the moon stays in its orbit because of the gravitational force it is subject to created by the Earth. It's all about gravity and force.


How do planets move if they are closer to the sun?

Planets closer to the sun move faster in their orbits due to the stronger gravitational pull from the sun. This increased speed helps to counteract the stronger pull of gravity, allowing them to maintain a stable orbit.


How does the orbits effect the way planets move?

Orbits help a planet move because of gravitational pull which makes the planet orbit round and round. The planets orbit around the son and the moon orbits around earth. Hope this helps!


What helps keep the planets orbiting the sun?

The planets orbit the sun due to gravitational attraction. The sun's massive gravity pulls the planets towards it, while the planets' tangential velocity allows them to move in a circular or elliptical orbit around the sun. It's essentially a balance between the inward force of gravity and the outward force of the planets' momentum.
