What effect do planets have on the stars they orbit?
The gravity of the star is usually many times larger than the planets due to the overwhelming mass of the star in comparison. The planets do have a gravitational pull of their own though, which has an effect on the star it is orbiting. It will cause the star to move slightly off centre as it pulls on the star during its orbit. The bigger the planet, the bigger the pull. By looking at distance stars, astronomers can see the effects of planets by observing a 'wobble' in the star as the unseen planets orbits it. They can then calculate the size of the planet and distance by the size and speed of the wobble.
Why does a star's wobble indicate that a planet is nearby?
A star's wobble can indicate the presence of a planet because the gravitational pull of the planet causes the star to move slightly as they both orbit around a common center of mass, or barycenter. By measuring the star's wobble, astronomers can detect the presence of an unseen planet based on the characteristics of the wobble.
Do an extrasolar planet and its parent star orbit around their center of mass at the same speed?
No, usually the star orbits more slowly due to its greater mass. The planet's orbit is affected by the star's gravity, causing the star to wobble slightly around the common center of mass. This wobble is used to detect exoplanets through the radial velocity method.
Does earth's wobble cause vertigo?
yes, it does.
What force acts between a planet and a star to cause variation in the motion of the star?
The effect on the star is usually quite small, but the force is "gravity".
What two factors cause a nebula to develop into a star?
The two main factors that cause a nebula to develop into a star are gravity and heat. Gravity pulls the gas and dust in the nebula together, causing it to collapse under its own gravity. As the collapse continues, the temperature and pressure in the core of the collapsing nebula increase, eventually reaching a point where nuclear fusion ignites, and a star is born.
Why does steering wheel wobble not car but steering wheel when wheels are straight?
The steering joints and connections are worn and need replacing Actually, the most likely problem is the tires. They may just need balancing. Sometimes the belts in the tires separate which causes a wobble. high/low spots in tires also causes a wobble. A bent rim can cause a wobble. Excessive negative caster will cause a wobble (alignment issue). Steering joints (inner and outer tie rods will not cause a wobble)
What happens if you launch a model rocket with no fins?
It Can Cause The Rocket To Spin Out, and/or wobble of course
How does gravity and nuclear fusion affect a stars size?
Gravity will cause a star to become smaller, because it pulls matter towards the star's core and causes it to contract. On the other hand, nuclear fusion will cause a star to become larger, because it produces an outward pressure, pushing the star's matter outwards and causing it to expand.
Why does a star wobble?
Yes, any star with heavenly bodie/S will exert a gravitational pull on the star. That Is actually how we discover planets orbiting stars outside of our solar system by looking for a slight wobble.
Can a bent rim cause a wobble while driving?
Yes is can.
One indication that a planet may exist near a distant star is that?
You can observe to see if a star appears to wobble over time, due to the gravitational pull of an orbiting planet. You can also obseve the light being emmited from the star. The intensity of light from a star can increase (not decrease) when a planet passes in front of the star relative to the observer. This is because the planet's gravity acts like a lens.
