Outer Space

A solar system is the collection of eight planets and their moons in orbit around the sun, together with smaller bodies in the form of asteroids, meteoroids, and comets. 

 The sun has a Gravity of around 274 m/s² with a Luminoity of around 1 L☉.  The sun also has a Mass of  around 1.989 × 10^30 kg

 with a Radius of around 432,690 mi. The sun has a Surface temperature of about 5,772 K . The sun is a medium sized star that is at the center of our solar system, the Sun contains about 92% hydrogen and 8% helium, with a tiny bit of the other common elements we find here on Earth.

Earth's radius is around 3,958.8 mi, the only known planet to sustain living organisms. 

The Earth also has an atmosphere that gets broken into the troposphere and stratosphere. In addition, there is the Mesosphere, Thermosphere, Ionosphere, and the Exosphere. The troposphere starts at the Earth's surface and extends 8 to 14.5 kilometers or 5 to 9 miles high. Then, it transitions into the Stratosphere, which begins just above the troposphere and extends to 50 kilometers or 31 miles high. The gravity on Earth is approximately 9.8 m/s^2 or 1g.

Does Earth have water? Yes, Earth has water. About 71 percent of Earth is covered in water, with only 2.5% being fresh water, while the other 96% is salt water. Only 29% of Earth is land. Is there any flora on Earth? Yes, plants make up 80% of the living things on Earth. Approximately 320,000 plant species are worldwide, with only five plant types living in the ocean.

Are there fauna on earth? yes, earth has animals.

About 15 % of life on Earth is marine life, although there are around 32,000 fish species and more than 50,000 shellfish Species.

More than 1 million species of insects make up 40% of all the living things on this planet. More than 5,400 mammal species make up 8% of the living things on this planet. Between 9,000 and 11,000 species of birds make up 0.08% of the residing organisms on Earth, although Approximately 10,000 reptile species live on this beautiful planet.

There are as many as 11 different biomes and three different types of ecosystems on Earth that the plants and animals call home.

A Black hole is a region of space having a gravitational field so intense that no matter or radiation can escape. Black holes are caused when giant stars collapse, and perhaps by other methods that are still unknown to astronomers.

A galexy is a system of millions or billions of stars, together with gas and dust, held together by gravitational attraction. there are  4 main types of galexies including the peculiar galexies, spiral galexies, iregular galexies and the Eliptical Galexies. There are roughly 200 billion galaxies in the observable universe according to astronomers.

Gravity is the invisible force that attracts a body toward the center of the earth or toward any other physical body having mass.

A star is a fixed luminous point in the night sky which is a large, remote incandescent body like our sun. there are approximately 200 billion trillion stars in outer space according to astronomers.
