1. Run the following query (inspired by this one) to get the list of exoplanets (Q44559) whose names start with "NAME":

   SELECT ?qid ?Len
   WHERE
   {
     ?qid wdt:P31 wd:Q44559;
           rdfs:label ?Len;
     FILTER (lang(?Len) = "en").
     FILTER regex (?Len, "^NAME").
   }

2. Download the output as a CSV file
3. In a text editor, convert the contents to the QuickStatements instructions format (replace the Wikidata item URLs with just the QID). Note: The query above is already designed to provide the correct header row for QuickStatements: qid (instead of ?item) and Len (instead of ?itemLabel).
4. Remove the "NAME " from the Len column
5. Paste the instructions into a new batch in QuickStatements, and execute it.
6. Do the same steps for unconfirmed exoplanet items (Q18611609).
