The quest to find life outside the solar system got a big boost with the discovery of seven Earth-size extra-solar planets, or exoplanets, orbiting a dwarf star about 40 light years away. Unlike earlier discoveries of exoplanets, all seven planets could possibly have liquid water — a key to life as we know it on Earth — with three planets having the greatest chance. This is by far the largest collection of Earth-like planets in the habitable 'Goldilocks' zone of a star — neither too close nor too far from a star, which raises the possibility of liquid water being present on the surface. Only Earth has liquid water in the solar system. Since the dwarf star is much cooler than the Sun, the dimming of light each time a planet passes or transits before the star could be easily recorded from Earth unlike in cases when planets transit a Sun-like bright star. Since the initial discovery of three planets was made using the Chile-based Transiting Planets and Planetesimals Small Telescope, the exoplanet system is called TRAPPIST-1.

Understanding Liquid Water in Our Solar System
Liquid water is considered essential for life as we know it, and its presence in the solar system is limited.
Current Knowledge of Liquid Water
- Earth: The only planet in our solar system known to have stable bodies of liquid water on its surface.
- Mars: Evidence suggests that Mars may have had liquid water in the past, and currently, there are indications of salty liquid water brines, but no stable bodies of liquid water exist today.
- Other Celestial Bodies: While some moons and planets may have subsurface oceans (like Europa, a moon of Jupiter), these do not count as surface liquid water.
Conclusion on Liquid Water Presence
Given the current understanding of our solar system:
- Only Earth has stable, surface liquid water.
- The statement in the passage is accurate, confirming that the answer to the question is option C: One.
This highlights Earth’s unique position in the solar system regarding the availability of liquid water, reinforcing the significance of the recent discovery of potentially habitable exoplanets in the TRAPPIST-1 system.
