One indication that a planet may exist near a distant star is that?
its gravity is strong enough to exert an effect on other objects in orbit.
A shadow appears between the star and the observer.
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.
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 &…
There are four ways in which an exoplanet can be detected. Transit method- a planet passes in front of the star making it detectable Astrometry- the center of mass near a star is shifted by a planet making the star wobble Doppler shift- the wave length of the radiation coming from the star will shift if there is a planet present Radial lensing- when looking at pictures of the distant star there will be a…
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.
