Since the discovery of the first extrasolar giant planets around Sun-like stars, evolving observational capabilities have brought us closer to the detection of true Earth analogues. The size of an exoplanet can be determined when it periodically passes in front of (transits) its parent star, causing a decrease in starlight proportional to its radius. The smallest exoplanet hitherto discovered has a radius 1.42 times that of the Earth’s radius (R⊕), and hence has 2.9 times its volume. Here we… 

Extrasolar planets: An Earth-sized duo

The first Earth-sized planets orbiting a Sun-like star outside the Solar System have at last been detected, and the radii of the planets and the architecture of the system suggest that the Earth-shaped planets are rocky, and that the outer planet may have developed a thick atmosphere of water vapour.

Below One Earth: The Detection, Formation, and Properties of Subterrestrial Worlds

The Solar System includes two planets—Mercury and Mars—significantly less massive than Earth, and all evidence indicates that planets of similar size orbit many stars. In fact, one of the first

The mass of the Mars-sized exoplanet Kepler-138 b from transit timing

The sizes and masses of three planets orbiting Kepler-138, a star much fainter and cooler than the Sun, are reported, determining that the mass of the Mars-sized inner planet, Kepler- 138 b, is Earth masses and its density is grams per cubic centimetre.

A SUPER-EARTH-SIZED PLANET ORBITING IN OR NEAR THE HABITABLE ZONE AROUND A SUN-LIKE STAR

We present the discovery of a super-Earth-sized planet in or near the habitable zone of a Sun-like star. The host is Kepler-69, a 13.7 mag G4V-type star. We detect two periodic sets of transit

A 1.9 Earth radius rocky planet and the discovery of a non-transiting planet in the Kepler-20 system

Kepler-20 is a solar-type star (V = 12.5) hosting a compact system of five transiting planets, all packed within the orbital distance of Mercury in our own Solar System. A transition from rocky to

Kepler-62: A Five-Planet System with Planets of 1.4 and 1.6 Earth Radii in the Habitable Zone

The Kepler mission detected a five-planet system where all the planets are smaller than twice the size of Earth and where the two outermost planets orbit in the habitable zone of their star, defined as the region where a rocky planet can host liquid water on its solid surface.

The Kepler Mission: Zeroing in on habitable Earths

NASA's Kepler Mission was launched on March 6, 2009 with the goal of determining the frequency of Earth-size planets in the habitable zone of solar-like stars using the transit photometry method.

FORMATION, TIDAL EVOLUTION, AND HABITABILITY OF THE KEPLER-186 SYSTEM

The Kepler-186 system consists of five planets orbiting an early M dwarf. The planets have physical radii of 1.0–1.50 R⊕ and orbital periods of 4–130 days. The 1.1 R⊕ Kepler-186f with a period of 130

KEPLER-68: THREE PLANETS, ONE WITH A DENSITY BETWEEN THAT OF EARTH AND ICE GIANTS

NASA's Kepler Mission has revealed two transiting planets orbiting Kepler-68. Follow-up Doppler measurements have established the mass of the innermost planet and revealed a third Jovian-mass planet
