Correct Answers

What is the name of the galaxy in which the Solar System is located?

The Solar System is one of the billions of star systems located in the Milky Way Galaxy. Scientists think that the Solar System formed about 4.5 billion years ago.

Which is the largest planet in the Solar System?

The largest planet in the Solar System is Jupiter. It is named after Roman mythology. As a gas giant, Jupiter’s atmosphere is composed mostly of hydrogen and helium, but also contains traces of methane and water vapor.

How old is the universe?

According to current information, scientists think that the universe is about 13.7 billion years old. The universe, which started to expand with an event called the Big Bang, continues to expand even after billions of years have passed. This energy, which forces the universe to expand, is called “dark energy”.

What is the most abundant element in the universe?

The most abundant element in the universe is hydrogen. Hydrogen, with atomic number 1, makes up about 3/4 of the universe by mass.

Which telescope was launched into space on December 25, 2021?

The James Webb Space Telescope was launched into space on December 25, 2021 and entered service on July 12, 2022. It is planned to remain in office for approximately 10 years.

How many billion years ago was the earth formed?

Earth was formed about 4.5 billion years ago. On Earth, where prokaryotes ruled for billions of years, the first animals appeared about 540 million years ago, and the first humans about 2.8 million years ago.

Which is not a trans-Neptune dwarf planet?

The main trans-Neptune dwarf planets are Pluto, Haumea, Makemake, and Eris. Ganymede is one of the moons of Jupiter, the largest planet in the Solar System. Although it is a moon of a planet, it is larger than Mercury.

Which is not one of Jupiter’s moons?

Jupiter’s most well-known moons are Europa, Ganymede, Io and Callisto. Deimos is one of the two natural moons of Mars. It is named after Deimos, the god of terror and fear in Greek mythology.

How many kilometers per second is the speed of light in vacuum?

The speed of light, accepted as the absolute speed limit in the universe, is about 300,000 kilometers per second. The distance of many celestial bodies in the universe is measured by the speed of light. For example, Alpha Centauri, the closest star to Earth after the Sun, is about 4.37 light years away from us. So if you can reach the speed of light, you can reach Alpha Centauri after 4.37 years. 4.37 light years is equivalent to 41.3 trillion km.

Because of the speed of light, we actually see the past appearance of everything in the sky. Namely, when we look at Alpha Centauri, we actually see it as it was 4.37 years ago. Because the light of 4.37 years ago is reaching us just now. Therefore, an observer near Alpha Centauri would also see the Earth as it was 4.37 years ago. Considering that the first humans appeared about 2.8 million years ago, it can be said that no hypothetical civilization more than 2.8 million light-years away could see humans.

Which is the brightest star in the sky?

The brightest star in the sky is Sirius. It actually consists of two stars, Sirius-A and Sirius-B, although it appears to be a single star from Earth. Its distance from Earth is about 8.6 light years.

Even if the speed of light is reached, how many years will it take us to reach the neighboring galaxy Andromeda?

Andromeda, the closest large galaxy to the Milky Way Galaxy, is about 2.5 million light-years away. Therefore, even if you reach the speed of light, your Andromeda journey would take about 2.5 million years. With a Lockheed SR-71 jet traveling at 3500 km per hour, it takes approximately 771 billion years.

What are the closest and farthest planets from the Sun?

The planets closest to the Sun are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune, in order.
