Minor-planet moon Herculina does not have a significant satellite. There were other similar reports of asteroids having companions (usually referred to as satellites) in the following years. Also, a letter in "Sky & Telescope" magazine at this time pointed to apparently simultaneous impact craters on Earth (for example, the Clearwater Lakes in Quebec), suggesting that these craters were caused by pairs of gravitationally-bound objects. In 1993, the first asteroid moon was confirmed when the Galileo probe discovered the small Dactyl orbiting 243 Ida in the asteroid belt. The second was discovered around 45 Eugenia in 1998. In 2001, 617 Patroclus and its
Craters of the Moon (geothermal site) Craters of the Moon (geothermal site) Craters of the Moon Thermal Area (or "Karapiti" in Māori language) is a region with geothermal activity north of Taupo, New Zealand. It is a part of Wairakei, the largest geothermal field in New Zealand, with a surface area of about 25 km2, which lies in the Taupo Volcanic Zone. The name springs from the many hydrothermal eruption craters, which are in part barren and which have bright colours. Combined with the numerous steam vents, constantly shifting, collapsing and reforming giving the whole area desolate appearance, and the sulphur smell, the whole area has
