Is Saturn the smallest planet?
If we put our planets in 'size order' they would be listed as the following, from large to small: Jupiter, Saturn, Uranus, Neptune, Earth, Venus, Mars, and Mercury. Since we lost Pluto as an official planet, it appears that Mercury is now considered the smallest planet in the solar system.
What is our galaxy name?
The Milky Way The Milky Way gets its name from a Greek myth about the goddess Hera who sprayed milk across the sky. In other parts of the world, our galaxy goes by other names. In China it's called the “Silver River,” and in the Kalahari Desert in Southern Africa, it's called the “Backbone of Night.”

What is the 2 smallest planet?
Closest to the sun, Mercury is the second smallest planet in our solar system. It has an orbital period of 87.97 Earth days and rotates on its axis once every 59 Earth days. The average surface temperature is 800 degrees Fahrenheit.
Is Neptune the smallest planet?
Neptune is the fourth largest planet in terms of diameter, making it the smallest in physical size of the gas giants. The average distance from the center of the planet to its surface is 15,299 miles (24,622 kilometers). But like most spinning bodies, Neptune's rotation causes it to bulge slightly around the equator.
Is there a black hole in Milky Way?
Today, the Milky Way galaxy possesses a supermassive black hole of 4.3 million solar masses. While this might seem tremendous, it's unusually small for a galaxy as massive as our own.
Why is the night sky dark?
During the day, sunlight floods our atmosphere in all directions, with both direct and reflected sunlight coming to us from everywhere we can see. At night, the sunlight doesn't flood the atmosphere, and so it's dark everywhere in the sky that there isn't a point of light at, like a star, planet, or the Moon.
What planet is the coldest?
Uranus The coldest planet in our solar system on record goes to Uranus which is closer to the Sun and 'only' about 20 times further away from the Sun than the Earth is. The lowest temperature recorded there was minus 224 degrees Celsius.
What is Earth’s twin planet?
Venus Venus is often called "Earth's twin" because they're similar in size and structure, but Venus has extreme surface heat and a dense, toxic atmosphere.
Is there only 1 SUn in the universe?
There are billions of stars larger or smaller than SUn in the Galaxy..But we call them stars only.. So we have only one Sun.
Does Saturn have 62 moons?
Saturn has 82 moons. Fifty-three moons are confirmed and named and another 29 moons are awaiting confirmation of discovery and official naming. Saturn's moons range in size from larger than the planet Mercury — the giant moon Titan — to as small as a sports arena.
Is Uranus smaller than Saturn?
Saturn is the second largest planet in our Solar System. It has a diameter of 120,536 km across the equator, and a surface area of 4.27 x 1010 km2. With a volume of 8.27 x 1014 km3, Saturn can hold 764 Earths inside. Uranus has a diameter of 51,118 km and a surface area of 8.1 x 109 km2.
Can you leave a galaxy?
The technology required to travel between galaxies is far beyond humanity's present capabilities, and currently only the subject of speculation, hypothesis, and science fiction. However, theoretically speaking, there is nothing to conclusively indicate that intergalactic travel is impossible.

Why is the sky pink?
Because there are more haze and dust particles hanging around during the summer season. According to studies, the atmosphere should contain more aerosols, to get a red or pink sky. Aerosols are fine solid or liquid particles in the air, arising from both natural and anthropogenic sources.
What color is space?
The blue color of the sky is a result of this scattering process. At night, when that part of Earth is facing away from the Sun, space looks black because there is no nearby bright source of light, like the Sun, to be scattered.
