Absolutely stunning. Baby Bear is too little, so he can't do as much as Mummy Bear can. Mummy Bear shows him what it's going to be like to be tall and fast, able to dive into the sea and swim strongly, but she tells him she doesn't want him to grow up just yet because she likes being able to snuggle him. He agrees - although it's going to be fun to be big, he doesn't want to be big right now. Comments have to be in English, and in full sentences. They cannot be abusive or personal.

Marking the Little Bear's tail, [16] Polaris, or Alpha Ursae Minoris, is the brightest star in the constellation, varying between apparent magnitudes 1.97 and 2.00 over a period of 3.97days. [24] Located around 432 light-years away from Earth, [25] it is a yellow-white supergiant that varies between spectral types F7Ib and F8Ib, [24] and has around 6times the Sun's mass, 2,500times its luminosity, and 45times its radius. Polaris is the brightest Cepheid variable star visible from Earth. It is a triple star system, the supergiant primary star having two yellow-white main-sequence star companions that are 17 and 2,400 astronomical units (AU) distant and take 29.6 and 42,000years respectively to complete one orbit. [26] RW Ursae Minoris is a cataclysmic variable star system that flared up as a nova in 1956, reaching magnitude 6. In 2003, it was still two magnitudes brighter than its baseline, and dimming at a rate of 0.02 magnitude a year. Its distance has been calculated as 5,000±800parsecs (16,300light-years), which puts its location in the galactic halo. [56]Döllinger, M. P.; Hatzes, A.P.; Pasquini, L.; Guenther, E. W.; Hartmann, M.

Traditionally called Kochab, Beta Ursae Minoris, at apparent magnitude 2.08, is slightly less bright than Polaris. [27] Located around 131light-years away from Earth, [28] [d] it is an orange giant—an evolved star that has used up the hydrogen in its core and moved off the main sequence—of spectral type K4III. [27] Slightly variable over a period of 4.6days, Kochab has had its mass estimated at 1.3times that of the Sun via measurement of these oscillations. [29] Kochab is 450 times more luminous than the Sun and has 42 times its diameter, with a surface temperature of approximately 4,130K. [30] Estimated to be around 2.95billion years old, ±1billion years, Kochab was announced to have a planetary companion around 6.1times as massive as Jupiter with an orbit of 522days. [31] Ursa Minor and Ursa Major in relation to Polaris Brown points out that Aratus fittingly describes "Cynosura" as "high-running" ("at the close of night Cynosura's head runs very high", κεφαλὴ Κυνοσουρίδος ἀκρόθι νυκτὸς Look up into the night sky and see the Great Bear and the Little Bear.

Big Bear, Little Bear is a simple board book with a sweet take on contrasts, featuring a parent and child from Marine Schneider. Ursa Minor is rather devoid of deep-sky objects. The Ursa Minor Dwarf, a dwarf spheroidal galaxy, was discovered by Albert George Wilson of the Lowell Observatory in the Palomar Sky Survey in 1955. [67] Its centre is around 225 000 light-years distant from Earth. [68] In 1999, Kenneth Mighell and Christopher Burke used the Hubble Space Telescope to confirm that the galaxy had had a single burst of star formation that took place around 14billion years ago and lasted around 2billion years, [69] and that the galaxy was probably as old as the Milky Way itself.
