On the way to Pluto: beyond Jupiter (4)
|
Caption NASA:"This image shows New Horizons' Current Position (end of February, 2007). The green segment of the line shows where New Horizons has traveled since launch; the red indicates the spacecraft's path toward Jupiter, Pluto and beyond. Positions of stars with magnitude 12 or brighter are shown from this perspective, which is above the Sun and "north" of Earth's orbit.
AU -> The graphics on these pages note New Horizons' distance from Earth, Jupiter and Pluto in AU, or Astronomical Units. One AU is the average distance between the Sun and Earth, about 93 MMs or 149,6 MKM.
HV -> The Current Position graphic also notes the spacecraft's Heliocentric Velocity - HV, such as its speed with respect to the Sun - in kilometers per second.
One kilometer per second is equivalent to 0,62 miles per second, or 2237 miles per hour".
