When you click on the date-button, a small popup input box
appears in the upper left corner of your screen (sometimes barely visible)!
Use the horizontal scrollbar to rotate, use the vertical scrollbar to flip the 3D-view.
Move the zoom-scrollbar to the right to increase the zoom into the inner solar system or to the left to decrease the zoom.
0° Aries or vernal equinox is where the red line points to, on default it points to the left side.
When you activate 'Zodiac Grid' you get the ecliptic plane divided into the twelve equal 30°-sections of the zodiac.
Zodiac color-code: red for fire-signs, green for Earth-signs, yellow for air-signs and blue for water-signs.
When you move the zoom-scrollbar to the left then you see the zodiac-abbrev.
Object Nodes: the intersection of the object's orbit plane with Earth's orbit plane is shown.
'South node' => object intersects fom south to north, 'North node' => object crosses Earth's plane from northern to southern latitude.
Object Apsides: the orbit points where the object's orbit has its farthest distance from the Sun (called Aphelion)
or nearest distance towards the Sun (called Perihelion) are shown.
Object's Apogee/Perigee: the orbit points where the object's orbit has its farthest distance from Earth (called Apogee)
or nearest distance towards Earth (called Perigee) are shown.
An underscore at the beginning of a provisional designation means that it has no MPC-catalog number yet.
