What are the 13 planets in our solar system?
Order Of the Planets From The SunMercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
An easy mnemonic for remembering the order is “My Very Educated Mother Just Served Us Noodles.”Mercury: …
Is Venus the closest to the sun?
At an average distance of only 57.9 million km, Mercury orbits closer to the Sun than any other planet. Just to give you a comparison, Venus orbits the Sun at an average distance of 108.2 million km. … And then Venus is the second closest planet to the Sun, and Earth is the third closest planet to the Sun.
How many galaxies are there?
Research released in 2016 revised the number of galaxies in the observable universe from a previous estimate of 200 billion (2×1011) to a suggested two trillion (2×1012) or more and, overall, as many as an estimated 1×1024 stars (more stars than all the grains of sand on planet Earth).
Which planet is the hottest in our solar system?
VenusPlanetary surface temperatures tend to get colder the farther a planet is from the Sun. Venus is the exception, as its proximity to the Sun and dense atmosphere make it our solar system’s hottest planet.

What is the second closest star to the sun?
In 2016, astronomers discovered a planet orbiting Proxima Centauri, the nearest star to our sun, just 4 light-years away. Now, they believe they have found an exoplanet around Barnard’s star, which at 6 light-years away is the second-closest star system.
What is the closest planet to the sun?
Introduction.The smallest planet in our solar system and nearest to the Sun, Mercury is only slightly larger than Earth’s Moon.From the surface of Mercury, the Sun would appear more than three times as large as it does when viewed from Earth, and the sunlight would be as much as seven times brighter.More items…
Why do stars twinkle?
As light from a star races through our atmosphere, it bounces and bumps through the different layers, bending the light before you see it. Since the hot and cold layers of air keep moving, the bending of the light changes too, which causes the star’s appearance to wobble or twinkle.

Does the sun shine in space?
The astroid, plants and planet’s moon shines by the photons released from the Sun(i.e light particles). As there is nothing else in space to shine, hence we never see the Sun’s light. Everything you see is in space, I mean the Sun, earth and other planets. Every 2 planets have huge distance between them.
How far is the next closest star?
Is it possible? No one knows yet, but Alpha Centauri is an obvious target. It’s the nearest star system to our sun at 4.3 light-years away. That’s about 25 trillion miles (40 trillion km) away from Earth – nearly 300,000 times the distance from the Earth to the sun.
