Interplanetary space is the area between planets in the solar system. Moving up on the scale is interstellar space or the area between stars within the same galaxy. Finally, the largest physical space is the area between galaxies themselves which is called intergalactic space!
Scientists generally agree today that comets were formed at the same time that our solar system was formed – about 4.6 billion years ago. At that time, the solar system was an enormous spinning disk of dust and gas called the Solar Nebula. Over time, gravitational attraction caused the dust and gas in the center to form our Sun and other areas consolidated into clumps of matter called planetesimals. Planetesimals were about one kilometer across.
Spring begins with the vernal equinox which occurs on March 20th in the Northern Hemisphere. This change heralds the rise of the spring constellations and sadly, we have to say goodbye to the bright stars of winter including the awesome Orion constellation.
If you are lucky enough to live in the northern hemisphere and even luckier to live near the arctic circle, this is prime time for viewing the Aurora Borealis. For some unknown reason, the Aurora Borealis seems to be more active during the spring equinox.
Saturn has the most extensive and complicated ring system of any planet in our solar system. These beautiful rings are primarily made up of particles of ice ranging in size from micrometers to meters. They also contain dust and other chemicals
