Astronomy and Space Questions Answer

No.-1. What is a supernova?

Answer: Supernovae are exploding stars, or the explosion of a star that is at least ten times larger than the Sun

No.-2. What is a planet?

Answer: A planet is a big body that orbits the sun in space. The most popular planets are named after Roman gods, such as “Jupiter”. Uranus and Neptune are not named after Roman gods, but are called “ice giants”

No.-3. What is a galaxy?

Answer: The galaxies are the large systems of stars, gas and dust. The word galaxy comes from the Greek galaxias which means ‘the milky one’, since when we observe the sky with our naked eyes almost all the stars seems to form a white streak of light formed by a lot of small points.

No.-4. What are planets made of?

Answer: Planets are made out of rock, gas, and sometimes ice. Giant planets have mostly gas and ice, while smaller ones have a lot more rock. All the planets together added up would make up less than one percent of the solar system!

No.-5. What is Nebula?

Answer: A nebula is a glowing cloud of gas in outer space that is sometimes called “the birthplace of stars”. There is no proof to show why they have this name though, because no one really knows exactly how they are created or why it happens in space.

Space Quiz Question

No.-6. What is a comet?

Answer: A comet is a giant ball of ice and dust that travels in an elliptical orbit around the Sun. There are four kinds of comets: short-period comets, long-period comets, Halley-type comets, and Jupiter-family comets. Sometimes they can be seen from Earth with a telescope if they orbit close enough to Earth. It is possible to see them when they pass by the Sun or even at night in the sky.

No.-7. What happens to comets after they have gone by the sun?

Answer: After they go by the sun, some end up as meteor showers.

No.-8. What are the two most dangerous objects in space?

Answer: The most dangerous objects in space are asteroids and comets. Asteroids and comets are usually too small to be seen by scientists, but sometimes they are big enough to destroy our planet! ice

No.-9. What are the four largest planets?

Answer: The four largest planets in order of size are Jupiter, Saturn, Uranus, and Neptune.

No.-10. What is a star?

Answer: Stars are huge balls of gas that produce heat and light by taking in more matter than they give off. They can come in different colors such as white, blue, red or even yellowish orange(called a ‘giant’ star). The Sun is a medium-sized star. These stars have been around for billions of years but eventually, their fuel will run out and they will become cold and black-dead stars called ‘white dwarfs’.

Astronomy Quiz

No.-11. What is a black hole?

Answer: A black hole is an object so dense that even light cannot escape its gravitational pull. There are two kinds of black holes, ‘stellar’ and ‘supermassive’. A stellar black hole forms when a star dies and collapses in on itself, while a supermassive black hole forms when several stars collide and create an object so dense that nothing can escape it. They are invisible because the light from the objects behind them cannot reach us. It is impossible to know if one exists in our galaxy but it has been found in other galaxies. (Artist’s concept of a supermassive black hole)

No.-12. What is a binary star system?

Answer: A binary star system is when two stars are close enough to their own orbit that they will live together. They are connected by the glue of gravity and will orbit together as long as they live, which could be millions or even billions of years!

No.-13. What are the main parts of the universe?

Answer: The universe as we know it is made up of three main parts: the solar system, the galaxy, and the universe. The solar system is made up of the Sun, planets and other bodies that orbit around it. Galaxies are small systems that have like thousands of stars in them and can contain a hundred billion to a trillion or more stars! Then there are galaxies that make a group called a cluster, which is made up of groups of clusters. These clusters eventually make up what we call the universe, which has an unknown amount of galaxies in it.

Astronomy And Space Quiz

No.-14. What are the planets’ colors?

Answer: The Solar System is made up of eight planets and their moons. They are: Mercury is Greenish-Black, Venus is a bright yellowish color, Earth is Burnt Orange, Mars a powdery red sand color, Jupiter a medium brown color, Saturn a light blue with many rings around it. Uranus Purple with many rings around it. And Neptune very whitish-blueish-green and has many dark blue rings around it.

No.-15. What are the planets’ sizes and how long do they take to orbit the sun?

Answer: Mercury and Venus are closest to the Sun at 36 million km (24.8 million mi) from the Sun. Earth is at 150 million km (93 million mi). Mars is at 228,000,000 km. Jupiter is at 778 million km. Saturn

No.-16. What are the sun’s colors?

Answer: Technically, the Sun is “White”. The Sun actually gives off all the colors in the rainbow. That is why you can see a rainbow right after it rains. When all of its colors are blended together, we see white.

No.-17. Do the planets have moons?

Answer: The planets in our solar system that have moons are Jupiter, Earth, Mars, Saturn and Neptune.

Space and Astronomy questions

No.-18. What are the differences between a planet and a star?

Answer: Planets orbit around stars (called suns). The planets we know of orbit the sun in an oval or circular path. Moons also orbit around planets. Planets are made out of matter that is heavier than gas. A star is made out of gases such as hydrogen, helium and oxygen. A planet can also be smaller than a star at times.

No.-19. Why do some people think that Pluto is not a planet?

Answer: Pluto was originally thought to be the planet farthest from the Sun. However, in 2005, scientists discovered another planet farther away from the sun than Pluto. Now astronomers are debating whether or not to make Pluto one of the smaller bodies orbiting the sun instead of a planet. Some people say that Pluto does not go around (or orbit) the Sun because it is too small to do so and that it should be put with other smaller bodies such as comets, asteroids and meteoroids instead of planets.

No.-20. What was the first planet discovered?

Answer: William Hershel, an English astronomer, discovered Uranus while stargazing through a telescope in 1781.
