K2 will
identify high-value exoplanets for follow-up and characterization
, collecting photometric information on tens of thousands of stars in the local neighborhood, and gathering information on stellar clusters, black holes, supernovae, and variable galaxies.
When did K2 mission end?
| Spacecraft properties | Entered service May 12, 2009, 09:01 UTC | End of mission | Deactivated November 15, 2018 | Orbital parameters |

What is Kepler K2 mission?
The K2 mission provides
an opportunity to continue Kepler’s ground-breaking discoveries in the field of exoplanets and expand its role into new astrophysical observations
. … It will observe tens of thousands of stars per campaign and will transmit science data to the ground once every 80 days.
How many planets did K2 discover?
| Confirmed Planets Discovered by K2 1 463 | K2 Candidates Yet To Be Confirmed 889 | K2 Campaign 9 Microlensing Events 627 | 1 This is the number of planets that were discovered utilizing Kepler/K2 observations. |

Where is Kepler now?
Kepler orbits the sun, and is currently located
around 100 million miles from Earth
.
How do we use Kepler’s laws today?
These laws can be
applied to model natural objects like planets, stars, or comets
, as well as man-made devices like rockets and satellites in orbit. Although Kepler originally developed his laws in the context of planetary orbits, the results hold for any system with a radial force obeying the inverse square law.
How many planets did Kepler discover?
During 9.6 years in orbit, Kepler led to the discovery of
more than 2,600 planets
by observing more than half a million stars.
Is Kepler still active?
The agency announced on Oct. 30, 2018, that Kepler has run out of fuel and
is being retired within its current and safe orbit
, away from Earth. Kepler leaves a legacy of more than 2,600 exoplanet discoveries. … NASA has decided to retire the spacecraft within its current, safe orbit, away from Earth.
How long was K2 expected to continue operating?
The Kepler spacecraft, operating as the K2 mission, will spend
three years
observing a ribbon of the sky (blue line) as it orbits the sun.
How many planets are there in the universe?
| Planetary system | Known planets 8 (Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune) | Known dwarf planets 2 universally accepted (Pluto Eris) 1 more likely to be (Ceres) 2 more possible to be (Haumea Makemake) | Known natural satellites 575 (185 planetary 390 minor planetary) | Known minor planets 796,354 |

What is a Tess confirmed planet?
The Transiting Exoplanet Survey Satellite (TESS) is
designed to discover thousands of exoplanets in orbit around the brightest dwarf stars in the sky
. In its prime mission, a two-year survey of the solar neighborhood, TESS monitored the brightness of stars for periodic drops caused by planet transits.
Can a planet orbit two stars?
It’s possible for a planet to orbit two stars at once
, causing extraordinary cosmic dances to occur. What weird orbits might be possible around binary stars? While the majority of exoplanets discovered are around single stars, many in our Galaxy are part of binary or multiple systems.
How many galaxies are there?
The deeper we look into the cosmos, the more galaxies we see. One 2016 study estimated that the observable universe contains two trillion—or
two million million
—galaxies. Some of those distant systems are similar to our own Milky Way galaxy, while others are quite different.
What will replace the Kepler telescope?
A replacement: Several exoplanet-hunting missions are in the works, including the
James Webb Space Telescope
, now due to launch in 2021 after a series of delays. NASA’s newest planet hunter, the Transiting Exoplanet Survey Satellite, launched in April.
How far can the Hubble telescope see?
The farthest that Hubble has seen so far is
about 10-15 billion light-years away
. The farthest area looked at is called the Hubble Deep Field.
