It took humans thousands of years to explore our own
planet and centuries to comprehend our neighboring planets,
but nowadays new worlds are being discovered every
week. To date, astronomers have identified more than
370 “exoplanets,” worlds orbiting stars other than the
sun. Amid such exotica, scientists are eager for a hint of
the familiar: planets resembling Earth, orbiting their stars
at just the right distance―neither too hot nor too cold―
to support life as we know it. No planets quite like our
own have yet been found, because they’re inconspicuous.
To see a planet as small and dim as ours amid the
glare of its star is like trying to see a firefly in a fireworks
play; to detect its gravitational influence on the star is
like listening for a cricket in a tornado. Yet by pushing
technology to the limits, astronomers are rapidly
approaching the day when they can find another Earth
and interrogate it for signs of life.

Astronomers have found more than 370 exoplanets orbiting the sun.

Planets like Earth have not been found because they are not easily observable.

The gravitational influence of a small planet like Earth on its star is easily detected.

Thanks to the development of technology, astronomers have found some planets like Earth.
