The new planet was discovered by astronomers at the National Aeronautics and Space Administration (NASA). The space object almost resembles the shape of the Earth.
According to a report by CNN Indonesia on Saturday
(03/08/2019), a new planet the size of the Earth
found in the 53-year-old light star of the solar system. But some
on the day after the discovery of the study, life can happen to the 4 planets closest to the extreme.
it was detected using the Transiting Exoplanet Exploration Satellite (TESS)
NASA. The new world is seen orbiting a star along with the planet
which is much larger, warmer and smaller than Neptune.

The Cavlee Institute, Diana Dragomir said, was a milestone for
TESS, because it reveals the first and similar Neptune planet
"This is the tenth planet
confirmed and discovered by TESS, "he added.
Features of the New Planet
Astronomers have discovered HD 21749c
which takes about 8 days to orbit the host star and
its size is almost the same as Earth's diameter of 89 percent.
the new is expected to have a surface temperature of up to 800 ° F / 427 ° C. separately
that they also discovered the HD 21749b, a new world with a Neptune size
warming about 23 times the mass of Earth and a radius about 2.7 times larger than Earth
orbiting the host star every 36 days.
This is quite surprising,
because TESS is not designed to detect planets that need time
more than 10 days for the star's orbit.
However, this is one
new things in the world of space that need to be revealed.
Telescopes used in TESS
To find HD 21749c, para
NASA astronomers detect 11 periodic slopes in star brightness for
determined that the starlight was partially blocked by a new planet the size of the Earth.
TESS was created to do
a list of short targets for large spaces and ground telescopes for
explore it further.
Magellan II, size telescope
6.5 meters from the Las Campani Carnegie Observatory in Chile are used
to track TESS research data.
Host Planet Finder Spectrograph (PFS), a tool created by Shectman and Crane using a method created by Butler and his associates. In order for the instrument to confirm and signal that TESS has found the planet. ***
