Question #582e8

Answer 1

Confirmed exoplanets: More than a thousand.

Explanation:

Earlier, in the last decade of the last century, ground telescopes

could identify planets by observing dimming of starlight, when a

planet of a star moved in front of the star.

Some earlier discoveries include Jupiter-size 51 Pegassi b, HD

208458 b, 55 Cancri and HD 80606 b.

Now and then since the beginning of this century, satellite

telescopes, Kepler, TESS, CHEOPS. CoRot, and PLATO, are/were

after exoplanets.

There is a graphical depiction of recent Kepler discoveries, in the

order of magnitudes (in Earth-mass unit) 16.52-1.42, in

the article

The names of these exoplanets are Kepler 7b, 5b, 8b, 6b, 9b, 9c, 4b,

9d, 10b, 11b, 11c, 11c, 11d, 11e, 11f and 11g

The first four are more massive than our Jupiter.
