Project «Nine planets» is the brief survey of history, mythology and latest scientific researches of every planet and satellite in the solar system.

Multimedia survey on the site Astronet.

Geomagnetic field — magnetic field of the Earth — measured in any point of earth surface is the totality of several magnetic fields, generated by different sources. This fields superimpose and interact one with other. More than 90% of measured field is generated inside the planet and in the Earth crust.

Ionosphere — is a part of upper atmosphere, where the density of unbound electrons is enough to influence the wave transmission. Ionization depends, firstly, on Solar activity.

Information data bases of space geodesy and geodynamics:

• International earth rotation and reference system service, IERS.
• Ukrainian centre of earth rotation parameters defining.

Data bases of observation results, gained with the methods of space geodesy and geodynamics with stations of ukrgeokosmomerezha (data bases of the main astronomic observatory of NAS of Ukraine):

Short-time flashes, appearing in the terrestrial atmosphere when invading of fast-moving minute solid particle, were called meteors (rarely, meteors are miscalled «shooting stars»).

• Meteor shower calendar on the site of International Meteor Organization.
• Meteor shower observations on the site of Odessa Meteor Observatory.

• Data about solar activity on site of Russian WDC on Solar-Terrestrial Physics.
• The branch of Solar Physics of the Main Astronomic observatory.
• Data of Kharkiv station of Solar monitoring of Kharkiv astronomic observatory.
• Real time data about solar flares, solar space rays, geomagnetic storminess indeces on the site of Kharkiv astronomical observatory

Space rays — is a natural radioactivity of space, charged particle flux of the high energies, falling to the Earth from the space (primary rays), and also secondary particles flux, born in reactions in the upper strata of atmosphere.
