Earth vs. Venus: What's the Difference?

Edited by Aimie Carlson || By Janet White || Published on January 16, 2024
Earth is the third planet from the Sun with a diverse climate and abundant life, while Venus, the second planet, is known for its extreme temperatures and dense, toxic atmosphere.

Key Differences

Earth, our home planet, supports a vast range of life forms due to its moderate temperatures and presence of water, whereas Venus, often called Earth's 'twin', is inhospitable with a thick atmosphere mainly composed of carbon dioxide.
Earth's atmosphere, rich in nitrogen and oxygen, is essential for life, contrasting with Venus's dense atmosphere that creates a severe greenhouse effect, leading to surface temperatures hot enough to melt lead.
Earth has a protective magnetic field that shields it from harmful solar radiation, while Venus lacks a significant magnetic field, leaving it exposed to solar winds and radiation.
The Earth's surface is dynamic, featuring oceans, continents, and a variety of ecosystems, unlike Venus, whose surface is dry, rocky, and marked by numerous volcanoes and a lack of water.
Earth's rotation leads to a 24-hour day/night cycle, while Venus has an extremely slow rotation, making a day on Venus longer than its year.

Earth's surface is mostly covered by oceans.


Venus rotates in the opposite direction to most planets.
A day on Venus is longer than its year.


Earth's atmosphere is protective and life-sustaining.
Earth's atmosphere filters harmful solar radiation.


Venus is sometimes called Earth's 'twin' due to its similar size.
Despite being Earth's twin, Venus is vastly different in terms of environment.


Earth has a diverse range of ecosystems and climates.
From tropical rainforests to polar ice caps, Earth's climates vary greatly.

The land surface of the world.


Roman Mythology The goddess of love and beauty.


The softer, friable part of land; soil, especially productive soil.


The second planet from the sun, having an average radius of 6,052 kilometers (3,761 miles), a mass 0.82 times that of Earth, and a sidereal period of revolution about the sun of 224.7 days at a mean distance of approximately 108.2 million kilometers (67.2 million miles).


Any of the bivalve molluscs in the genus Venus or family Veneridae.


The goddess of beauty and love, that is, beauty or love deified.


One of the planets, the second in order from the sun, its orbit lying between that of Mercury and that of the Earth, at a mean distance from the sun of about 67,000,000 miles. Its diameter is 7,700 miles, and its sidereal period 224.7 days. As the morning star, it was called by the ancients Lucifer; as the evening star, Hesperus.


The metal copper; - probably so designated from the ancient use of the metal in making mirrors, a mirror being still the astronomical symbol of the planet Venus.


Any one of numerous species of marine bivalve shells of the genus Venus or family Veneridæ. Many of these shells are large, and ornamented with beautiful frills; others are smooth, glossy, and handsomely colored. Some of the larger species, as the round clam, or quahog, are valued for food.


The second nearest planet to the sun; visible as an early `morning star' or an `evening star'; rotates slowly clockwise (in the opposite direction from the normal rotation of the planets);
Before it was known that they were the same object the evening star was called Venus and the morning star was called Lucifer


Goddess of love; counterpart of Greek Aphrodite


Type genus of the family Veneridae: genus of edible clams with thick oval shells
