Source-derived summary

The Exoplanet Data Explorer / Exoplanet Orbit Database is a database listing extrasolar planets up to 24 Jupiter masses. It is no longer actively maintained.

Overview

"We have retained the generous upper mass limit of 24 Jupiter masses in our definition of a “planet”, for the same reasons as in the Catalog: at the moment, any mass limit is arbitrary and will serve little practical function both because of the sin i ambiguity in radial velocity masses and because of the lack of physical motivation.

The 13 Jupiter-mass distinction by the IAU Working Group is physically unmotivated for planets with rocky cores, and observationally problematic due to the sin i ambiguity. A useful theoretical and rhetorical distinction is to segregate brown dwarfs from planets by their formation mechanism, but such a distinction is of little utility observationally."

The database was updated to include new exoplanets and possible exoplanets, using data from other archives such as the Astrophysics Data System, arXiv and the NASA Exoplanet Archive. The database stopped being updated in mid-2018 and is no longer actively maintained.

Editorial summary

The public source identifies “Exoplanet Data Explorer” as database of exoplanets. This brief keeps that definition visible, then builds a research path around Exoplanet, Data and Explorer.

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current lead gives the account dated anchors—2018—that can be checked directly. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with Exoplanet, Data and Explorer providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Exoplanet Data Explorer”, the useful work is to connect “database of exoplanets” to the records capable of establishing context and consequence.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 22, 2026. The linked authority identifier is Q5420641. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2018.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
