Juniper Springs Recreation Area--which encompasses the spring, Juniper Creek, and adjoining camping and trails--is a popular recreation spot for swimming, canoeing, kayaking, camping, and hiking. [5] Swimming is particularly popular as the water is 72 degrees, 365 days a year. [6] The Juniper Springs canoe run is a nationally recognized attraction.
In contrast, the Lunar distance (LD or ), or Earth–Moon characteristic distance, is a unit of measure in astronomy. More technically, it is the semi-major axis of the geocentric lunar orbit . The lunar distance is on average approximately 385,000 km (239,000 mi), or 1.28 light-seconds ; this is roughly 30 times Earth's diameter or 9.5 times ...

The Sun's gravitational effect on the Moon is more than twice that of Earth's on the Moon; consequently, the Moon's trajectory is always convex [25] [26] (as seen when looking Sunward at the entire Sun–Earth–Moon system from a great distance outside Earth–Moon solar orbit), and is nowhere concave (from the same perspective) or looped.
The lunar distance is the angle between the Moon and a star (or the Sun). In the above illustration the star Regulus is used. The altitudes of the two bodies are used to make corrections and determine the time. In celestial navigation, lunar distance, also called a lunar, is the angular distance between the Moon and another celestial body.
Instead of sending NASA landers, the space agency is paying private companies to send their payloads to the Moon to prepare for the next human Moon landing in 2027.
English: Illustration of Earth and Moon at the average distance from each other (semi-major axis) as seen from distant space If the preview width is 800 pixels wide, then each pixel is 500 km on the preview. This image is almost identical in proportions to File:Earth-Moon2.jpg
Propagation time to the Moon and back ranges from 2.4 to 2.7 seconds, with an average of 2.56 seconds (the average distance from Earth to the Moon is 384,400 km). The Moon is nearly spherical, and its radius corresponds to about 5.8 milliseconds of wave travel time.
