A galaxy is a huge collection of gas, dust, and billions of stars and their solar systems, all held together by gravity. We live on a planet called Earth that is part of our solar system.
A galaxy is a group of stars, clouds of gas, and dust particles that move together through the universe. There are billions of galaxies in the universe. They probably formed billions of years ago, soon after the universe began. The Sun, Earth, and the other planets of the solar system are part of the Milky Way galaxy.
We live in one of the arms of a large spiral galaxy called the Milky Way. The Sun and its planets (including Earth) lie in this quiet part of the galaxy, about half way out from the centre.
The galaxy consists of all the solar systems, stars and planets, and galaxy in different shapes. The universe is all the space where all the galaxy and other matter are current; all the galaxy value is indirectly a part of the universe. Humans have expanded the discovery to even space boundaries.
A galaxy is a system of solar systems and other stars. Galaxies, like solar systems, are held together by gravity. In galaxies, the solar systems are separated by vast sections of mostly empty space. The galaxy that contains the Earth and its solar system is called the Milky Way.
Our solar system—which includes the sun, Earth, and seven other planets—is part of this galaxy, called … you guessed it … the Milky Way. The Milky Way contains hundreds of billions of stars like our sun.
The Milky Way has a mass of 1.5 trillion suns.
Today, we know from radiometric dating that Earth is about 4.5 billion years old. Had naturalists in the 1700s and 1800s known Earth's true age, early ideas about evolution might have been taken more seriously.
Earth is the third planet from the Sun with an approximate distance of 149.6 million kilometres (93.0 million miles), and is traveling nearly 2.1 million kilometres per hour (1.3 million miles per hour) through outer space.
According to Christian belief, God created the universe. There are two stories of how God created it which are found at the beginning of the book of Genesis in the Bible. Some Christians regard Genesis 1 and Genesis 2 as two totally separate stories that have a similar meaning.

How many countries are there in the world? A lot, and no, Nambia, Button, and Nipple are not among them. Anyhow, there are 193, 195, 237, 245, 248, or 253 countries in the world, depending on definition. 193 sovereign states are members of the United Nations, the world's largest intergovernmental organization.
For the first time, Canada takes the top overall spot as the number one country in the world in the 2021 Best Countries Report. After ranking second in 2020, Canada has surpassed Switzerland in the 2021 report followed by Japan, Germany, Switzerland, and Australia.

Denmark. Denmark is one of the very few countries in the world which does not celebrate Independence Day and instead celebrates Constitution Day on June 5. This day marks the anniversary of when their constitution came into power.
The PRC claims the de jure administration of Taiwan Province, as well as mainland-nearby islands of Kinmen and Matsu Islands, currently controlled by the Republic of China (ROC).
Following the passage of the Taiwan Travel Act by the U.S. Congress on March 16, 2018, relations between the United States and Taiwan have since maneuvered to an official and high-level basis. Both sides have since signed a consular agreement formalizing their existent consular relations on September 13, 2019.
