Earth vs Sun: Difference and Comparison

Seasons or even biodiversity are determined by the earth’s proximity to the sun and the quantity of daylight it gets. The tilt of something like the earth’s axis, not its proximity to the sun, determines how much sun a place experiences.

Between the Earth and the sun, there are a number of distinctions. Some are self-evident, some are not. And this article outlines all of the significant and striking contrasts between the two celestial bodies.

Key Takeaways

1. Earth is a planet in our Solar System that orbits around the Sun, while the Sun is the star at the center of our Solar System.
2. Earth has an atmosphere capable of supporting life, while the Sun is a massive ball of gas that provides light and heat to Earth.
3. Earth has one moon, while the Sun does not have any moons.

Earth vs Sun

The Sun is a massive, luminous ball of gas that generates energy through nuclear fusion and is the largest object in the solar system, making up 99% of its mass. The Earth is the only known planet to support life and rotates around the Sun once every 365.25 days, determining its climate and weather patterns.

Our homeland, Earth, is the closest planet to the sun.

While researchers keep looking for signs of life elsewhere in the cosmos, Earth maintains the only location where we’ve ever found life forms and a sustained environment to support the life forms dwelling inside it.

The Earth is the fifth-largest planetary body in the Solar-system.

It is smaller than just the four gaseous giant planets — Jupiter along with the beautiful Saturn, Uranus, and Neptune — but bigger than Mercury, Venus and Mars, the three remaining rocky planets, which are smaller and more toxic.

Conversely, the Sun is the star within which the Earth and the rest of the solar system orbit. The system’s dominating body accounts for more than 99 percent of the total volume.

The Sun is a massive form of energy, some of which is used to give Earth both the warmth and sunlight it requires to sustain life.

Comparison Table

Body	It is a Rocky Body with a mass of 5.972E24 kg	It is a gaseous heavenly body with 92% Hydrogen in it. The Sun is a star.
Atmosphere	Earth has one atmosphere with several layers in it.	The Sun has no atmosphere but it has eruptive solar flares around its surface.
Radius	6371 kms is the radius of Earth.	695,500 km
Composition	Rocks and water along with various organic and inorganic elements.	The Sun mostly consists of Hydrogen as well as Helium along with a little oxygen and Carbon Dioxide.
Origin Date	Around 4.5 billion years ago Earth was formed.	4.6 Billion years ago.

What is Earth?

The Earth is the planetary system’s highest-density massive body. The Earth orbits the sun and spins on its centre from west to eastward. The Earth rotates once every 24 hours and makes one trip around the sun every 365 days.

As a result, this period is referred to as a year. The third planetary body from the Sun is Earth. The sun shines on different regions of the globe, creating hourly climatic variations in the people who live there.

The Earth spins from west to east with an imaginary orbit running across both polar tips, the North and South Poles.

Because these poles are orthogonal to the equator’s line, the hypothetical line is known as the Earth’s axis of rotation, and it is fictitious. The Earth is essentially a solid object composed of saturated rocky bodies on which a person may exist and live.

The Earth completes one rotation around the Sun every 365 days, which is referred to as a year. The moon completes its rotation around the Earth in 29.53 days (about 30 days), and this timeframe is known as a lunar cycle.

The Sun is a star, whereas the Earth is a celestial body known as a planet. The earth is made up of various elements as a planetary body. It’s a solid block of rock that’s compacted.

It has an environment that is suitable for sustaining life and an atmosphere that acts as a natural shield against the harmful substances that come from outer space. As a result, it is an environment in which living things may thrive or live.

What is the Sun?

The Sun is a star that sits at the centre of the Solar System, surrounded by terrestrial planets. The sun resembles a massive orange gaseous ball, yet it is essential for life on Earth.

The size of the Sun is approximately 150 times that of the Earth. Although the sun is far distant, its rays strike the Earth as well as the moon at different vantage points.

The Sun is classed as a G2 V stellar star, with G2 denoting the second hottest star inside the yellow G class—surface temperatures of roughly 5,800 kelvins (K)—where V denotes a growth stage, or dwarf star, which is the most common star in this range of temperature due to its concentrated concrete body.

In terms of size, the sun is around 100 to 150 times larger than the Earth. This indicates that if you line up 100 copies of the Earth in a single direction and link the beginning and finish, the diameter of the Sun would be the same.

For 4.6 billion years, the Sun has indeed been blazing. In the centre, where the combustion is most fast, a significant amount of hydrogen has already been transformed into helium.

Helium clings to the surface, where it collects more energy than protons. This boosts the luminosity and elevates the centre heat.

Main differences Between Earth and Sun

1. The Earth is a planet, whereas the Sun is a star.
2. The Earth has sustainable life and a life-supporting environment in it, whereas the Sun is burning hot and does not support life.
3. The Earth is solid, whereas the Sun is gaseous, with 92 percent of hydrogen in it.
4. The Earth is around 100 to 150 times smaller than the Sun.
5. The Earth orbits the Sun, whereas the Sun Orbits nothing, it just rotates on its axis.
