It has seasons like the earth. Jupiter has more than 16 moons (卫星)and it is the biggest and heaviest planet. Saturn has more than 22 moons. The other planets, such as Uranus and Neptune, are all very far from the sun and very cold. We need a telescope(望远镜)to see them. A. ...
What is the closest planet to Neptune? Which planet is the most cratered of the terrestrial planets? What is the mass of the planet Saturn? What is the planet after Mars? Which planet is bigger: Earth or Venus? What are the two planets without moons?
What is the biggest asteroid in the Kuiper belt? What is the second largest body in the asteroid belt? What is the circumference of the asteroid belt? How many planets have an asteroid belt? How many planets are there before the asteroid belt?
all these details are seen separately.This is what happens when we look at something.Beams of light of different degrees of intensity, reflected from all parts of the object, strike the lens of the eye.The lens then gathers together the spots of light from these beams and focuses them on ...
These two are Tethys, the larger one in the foreground, and Janus, the smaller one in the background. But could moons such as these have moons of their own? NASA/JPL-Caltech/Space Science Institute If planets can have moons, could those moons have moons of their own? After all, ...

There are many different types of telescopes available for those interested in exploring the depths of the night sky.
National Academy of Sciencesin April, which used Insight seismic data to find more support fora liquidy corewith high percentages of sulfur and oxygen. This makeup is much less dense than Earth’s core, according to the research, pointing to different formation conditions in the two planets. ...
The sun is a G-type star or a yellow dwarf and a pretty average size on the cosmic scale. Some "hypergiant" stars are much, much larger. Perhaps the biggest star known is UY Scuti, which could fit more than 1,700 of our suns. (Some estimates for the size of UY Scuti put it ...
In planetary terms, it refers to the optimal range of distances from a star where conditions are just right for liquid water to exist.5. Gas giants Jupiter and Saturn protect Earth from bombarding asteroidsLife on Earth may not be possible without the two biggest gas giants in the Solar ...
