Table schema:
CREATE TABLE table_name_87 (named VARCHAR, name VARCHAR, diameter__km_ VARCHAR, longitude VARCHAR, latitude VARCHAR)

Question: What is the namesake of Ayashe at a longitude less than 270.7, latitude more than -47.1, and a diameter less than 7.2?
SQL: SELECT named AS after FROM table_name_87 WHERE longitude < 270.7 AND latitude > -47.1 AND diameter__km_ < 7.2 AND name = "ayashe"
