Earth is the only planet in the solar system where life is known to exist. It has a unique combination of conditions, such as liquid water, a stable atmosphere, and a suitable temperature range, that support the diverse forms of life found on our planet.
Potentially. A Goldilocks planet is a planet that orbits in its star's habitable zone, meaning it is at the right distance that temperatures could support liquid water. This does not necessarily mean that the planet is in that temperature range, as temperature also depends on the composition and density of the planet's atmosphere and even how light or dark the planet's surface is. Even if temperatures are in the right range, that still does not guarantee that the planet could support life.
The most critical factor that allows liquid water to exist is the average temperature of the planet. This is primarily dependent on the temperature of the star it orbits, and its distance from the star. Other lesser but important factors include atmospheric composition and pressure, rate of rotation, and inclination to the orbital plane.If our solar system is typical, there is a huge amount of water in space, but it is mostly frozen solid on far planets, asteroids, and comets (and in the rings of Saturn). The liquid phase requires a temperature that is warmer, but not too warm. Astronomers refer to the potentially human-habitable region around any given star as the "Goldilocks zone" or Liquid Water Belt.
No, aluminum is a solid at room temperature and will only become liquid when it reaches a melting point of 660.32°C (1220.58°F). It is not a liquid over a wide temperature range compared to other materials like water.
For life to exist, there must be a source of energy, liquid water, organic molecules such as carbon, a conducive environment with appropriate temperature range and pH conditions, and a genetic material for storing and transmitting information, such as DNA or RNA.

The three essential criteria for making a planet habitable are the presence of liquid water, a stable atmosphere, and a suitable temperature range for life to exist.

For liquid water to exist on Earth, the planet's surface temperature needs to be within a certain range to keep water in its liquid state. Additionally, Earth's atmosphere plays a crucial role in maintaining the right conditions for liquid water by regulating the temperature and pressure. The presence of Earth's magnetic field also helps protect water from being stripped away by solar winds.
Liquid water exists on Earth because the planet's temperature and atmospheric pressure are within a range that allows water to remain in a liquid state. The presence of the greenhouse effect helps regulate Earth's temperature, keeping it suitable for liquid water to be stable. Additionally, the abundance of water vapor in the atmosphere contributes to the formation of liquid water through processes like condensation.
No planet in our solar system has that as its full temperature range. Earth certainly has that temperature range, but it can get both hotter and colder than that.

Earth is the planet that is approximately 150 million km (93 million miles) from the sun, which allows for water to exist in solid (ice), liquid, and gas (vapor) states due to its moderate temperature range.

There is no known planet with that temperature (or even temputure) range.
