extra-solar planet.
which exoplanet is 'THE exoplanet'?
The darkest exoplanet is "TRES-2B".
No. An exoplanet is a planet outside of our Solar System.
51 Pegasi itself isn't an exoplanet, it's a Sun-like Star. But it does have an Exoplanet orbiting it, 51 Pegasi b (informally named Bellerophon.).
No. A moon is not a planet. An exoplanet is aplanet that orbits a star other than the sun.
Both exoplanet and extrasolar planet are planets that are outside the solar sysytem.
Yes. While we know relatively little about the atmospheres of individual expolanets, there is no reason an exoplanet couldn't have an exosphere.
We do not know enough about conditions on any exoplanet to determine if any would be suitable for humans.
yes
no cheat's. xD

The mass of an exoplanet is typically determined using methods such as the radial velocity technique, where the gravitational pull of the planet causes measurable wobbles in its host star's motion. Another method is the transit method, which measures the amount of starlight blocked when a planet passes in front of its star, allowing calculations of the planet's size and density. By combining these data, scientists can estimate the mass of the exoplanet. The mass is often expressed in relation to Earth's mass (e.g., in Earth masses or Jupiter masses).
