So far, Earth is the ONLY planet known for sure to harbor life.
As far as we know, life is not possible without water.
A duck has habitability to water.
Earth's magnetic field plays a crucial role in maintaining the atmosphere by shielding it from harmful solar radiation and charged particles. This protection helps sustain life on Earth by preventing the erosion of the atmosphere and protecting living organisms from potential genetic damage. Without the magnetic field, Earth's habitability would be significantly compromised.

Curiosity, the Mars Science Laboratory rover, was launched from Earth on November 26, 2011. It successfully landed on Mars on August 6, 2012, with the mission to explore the planet's surface and assess its habitability.
The planet you are referring to is likely Kepler-452b, which is located about 1,400 light-years away from Earth. It was discovered by NASA's Kepler Space Telescope and is considered a "cousin" to Earth due to its potential habitability.
EVE (Extraterrestrial Vegetation Evaluator) , mission is to find evidence of life such as vegetation for purposes of habitability .
Anaerobic metabolisms and asexual reproduction
It is currently unknown if humans can live on a super-earth planet as it would depend on various factors such as atmosphere composition, gravity, temperature, and presence of water. More research and exploration of super-earth exoplanets are needed to determine their habitability for humans.
The Earth's energy budget refers to the balance between the amount of energy coming into Earth from the sun and the amount of energy being emitted back into space. This balance is crucial for maintaining Earth's climate, weather patterns, and overall habitability for life. Understanding and monitoring the Earth's energy budget helps scientists assess the impact of human activities on the planet's energy balance and climate system.
Humans have explored Mars and Venus with space probes. From Mars missions, scientists hope to learn about the planet's potential for past life, its climate history, and its geology, which may provide insights into Earth's own history. For Venus, missions aim to understand its extreme atmosphere, geological activity, and the possibility of past habitability, which can inform our understanding of planetary evolution and habitability in the solar system.
Presence of liquid water on the planet, indicating potential for habitability. Detection of organic molecules, suggesting the possibility of past or present life. Geological features resembling those on Earth where life thrives. Survival of extremophiles on Earth in extreme conditions, raising the possibility of similar life forms on Mars.
