They don't. They reflect light from the sun.
Telescopes are commonly used to observe and study bodies in outer space, such as stars, planets, galaxies, and other celestial objects. Different types of telescopes, like optical, radio, and space-based telescopes, offer unique perspectives and capabilities for exploring the universe.
Rigel appears as bright as Betelgeuse because it is hotter and more luminous, even though it is smaller. The luminosity of a star depends on both its temperature and size, so a hotter, more luminous star can shine as brightly as a larger, cooler star.
oh yes, all the way, they are SO heavenly filled with bodies of the heavens, that even i cant stand the heavenliness! :0 Planets ARE heavenly bodies, as are stars. Some planets have satellites, and some don't.
Planets do not exist on other bodies, they orbit the sun independent of one another. The planets are easily visible from the moon. In fact they are probably even more easily seen than they are from Earth due to the moon's lack of an atmosphere.
Even Serpents Shine was created on 1979-03-09.
It's possible that some stars do not have planets, or at least bodies that we would consider planets. But it is hard to imagine that any star could have absolutely nothing orbiting it, and therefore part of its 'system'. Any star would have countless bodies (presumably) of varying sizes and composition, and even possibly some bodies that have water and some signs of past/present life.
Here is a very singular thing: the Glow-worm's eggs are luminous even when still contained in the mother's womb.
This process is called accretion. It occurs when small particles in space are pulled together by gravity to form larger bodies, such as planets. As these bodies grow in size, their gravitational pull increases, allowing them to accrete even more material from their surrounding environment.
It normally depends upon what it is. Even though they aren't considered heavily, there are many objects out there such as dwarf planets and comets.
because there is no light for it to reflect off
That's right. But the sun shines on them and lights them up. The same reason you can see a rock in a dark room when you shine a flashlight on it, even though the rock does not produce light.
Among our sun's planets, Neptune enjoys that distinction. If we include dwarf planets, then Eris makes the longest journey (so far). We will likely discover icy bodies as big as Eris even further away.
