Question: What is the total stellar mass of the type M0?
SQL: SELECT SUM("Stellar mass ( M☉ )") FROM "2-10932739-3" WHERE "Type" = 'M0';

Question: What is the highest planetary mass having an RV (cm/s) of 65 and a Period (days) less than 21?
SQL: SELECT MAX("Planetary mass ( M⊕ )") FROM "2-10932739-3" WHERE "RV (cm/s)" = 65.0 AND "Period (days)" < 21.0;

Question: What is the smallest period (days) to have a planetary mass of 1, a stellar mass greater than 0.21 and of the type M0?
SQL: SELECT MIN("Period (days)") FROM "2-10932739-3" WHERE "Planetary mass ( M⊕ )" = 1.0 AND "Stellar mass ( M☉ )" > 0.21 AND "Type" = 'M0';
