Missing Kepler Targets

Problem description

I’m not sure where lightkurve resolves its targets from but all these Kepler targets don’t resolve:

‘Kepler-1663’,‘Kepler-1664’,‘Kepler-1665’,‘Kepler-1666’,‘Kepler-1667’,‘Kepler-1668’,‘Kepler-1669’, ‘Kepler-1670’,‘Kepler-1671’,‘Kepler-1672’,‘Kepler-1673’,‘Kepler-1674’,‘Kepler-1675’,‘Kepler-1676’,‘Kepler-1677’,‘Kepler-1678’,‘Kepler-1679’, ‘Kepler-1680’,‘Kepler-1681’,‘Kepler-1682’,‘Kepler-1683’,‘Kepler-1684’,‘Kepler-1685’,‘Kepler-1686’,‘Kepler-1687’,‘Kepler-1688’,‘Kepler-1689’, ‘Kepler-1690’,‘Kepler-1691’,‘Kepler-1692’,‘Kepler-1693’,‘Kepler-1694’,‘Kepler-1695’,‘Kepler-1696’,‘Kepler-1697’,‘Kepler-1698’,‘Kepler-1699’, ‘Kepler-1700’,‘Kepler-1701’,‘Kepler-1702’,‘Kepler-1704’,

There are also other target categories besides “Kepler” that do not resolve. Kepler are the easiest to show the issue with.

Example

Print a list of all target entries

target1 = “Kepler-1700”

print(“Target: " + str(target1)) search_result = lk.search_lightcurve(target1) print(search_result) print(”\n")

Target: Kepler-1700
Could not resolve Kepler-1700 to a sky position.
SearchResult containing 0 data products.

#### Expected behavior
See attached

#### Environment

-  platform (OSX):
-  lightkurve version (2.0.11):
-  installation method (pip):

It uses MAST name resolver, which relies on Simbad and NED to turn names into coordinates. Kepler-1700 doesn’t resolve by Simbad, thus it doesn’t resolve in MAST, thus it doesn’t resolve in lightkurve. If you know the KIC ID, all of those will resolve because “KIC xyz” uses the Kepler Input Catalog at MAST to translate it into a coordinate. The “Kepler-xyz” identifiers are assigned by NExScI and thus aren’t maintained by MAST.

It would be nice to be able to explore all the exoplanets currently listed in the below catalog with lightkurve
