We report the detection of the radar echoes from the data obtained with 34 m antenna at Kashima. The asteroid 6489 became the first solar system object observed by means of radar technique in Japan and it was a quite important step towards the future radar observations of asteroids. Although the observations were short duration for test and demonstration purposes, we could retrieve information about the size and reflectivity of the asteroid.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
