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.
Perturbation of the position of the star due to the gravity effect of the planet on the star's position, or a cyclic slight reduction of light coming from the star as a result of the transit of the planet across the face of the star.
Telescopes currently aren't powerful enough to see the planets directly. They aren't big enough to reflect sunlight & be seen so far away. The only way so far we can detect planets is indirectly by seeing if the star(s) it orbits causes a slight shift in the star's wobble or dims the star's brightness slightly kind of like a lunar or solar eclipse. Although, there's a telescope that has been launched to detect exoplanets & Earth-like planets, but I don't remember what it's called. Launched in 2010 or something.
Astronomers can detect the dim companion by observing the effects of its gravity. The dim star's gravity causes the bright star to wobble. Astronomers use this same method to detect planets around other stars
its gravity is strong enough to exert an effect on other objects in orbit.
A shadow appears between the star and the observer.
the star has very strong gravity
Yes -gravity. (please note that there's probably not any rocks traveling in a straight line) If it comes near a planet it will be attracted, if the attraction is sufficient, they will collide.
Uhm I am pretty sure that it is Jupiter....buht you may want to check my answer.
It would be stronger as you approach the Equator of the planet.
A repulsive force would exist as like charges always repel each other.
magnitude - 9.8 m/s2 direction - towards the center of the earth On or near the surface of the Earth, it's 9.8 meters (32.2 feet) per second2 , nominally toward the center of the Earth. On or near other planets, the number is different, and the direction is nominally toward the center of that planet.
If a distant star has a slight back and forth motion then it may be located near a planet. The gravitational force of the planet will cause the star to move.
No we are not and in the not to distant past everyone on the planet was terrified to go near us from the vikings to the romans
It is very unlikely that there is any life at all on Pluto. It is too small, it is too distant from the sun, and it probably doesn't have anywhere near the right materials.
antonym: near, close
Near object form bigger angle and distant objects form smaller angle. From this angle formed, you can judge the distance between near and distant objects. But their is limit to the smallest angle, you can perceive. That is why you can not note difference between the near and distant stars.
mars
synonym = far antonym = close, near
No. White lights are not an indication of ghosts.
Titan orbits the planet Saturn.
Earth
Mercury
The climate of a planet depends a lot on its surroundings. Does this planet have an atmosphere? If not, climate cannot exist (like the moon). If there's lots of water on this planet, there's a good chance it will be rainy season all year round. It also depends on the distance from the sun. If the planet's near the sun, it will be warmer, if it's farther, it will be colder.
