- Real orbits take hours, days or years, so time runs faster here. Time ×1,000 means each second on screen is 1,000 seconds (about 17 minutes) in space. The planet's turning is sped up by the same amount. The numbers shown are always the real ones.

Earth does the same thing, just gently because its orbit is almost circular: it moves about 30.3 km/s in early January and about 29.3 km/s in early July.
Gusobanukirwa
i Itandukanya ("", Ki/ bishaje ijambo ya:) i Umuvuduko Ku Icyo ari cyo cyose Akadomo:
v = √( μ · (2/r − 1/a) )
- v: Umuvuduko

Kugenzura…
- Uruziga (R = A): V = (μ A). ni i Umurongo: Ibipimo Kuva: i.
- Kuri, R ni, 2 / R ni na V ni.
- ku Inzira (A →): V = (2) ni i Kwiruka Umuvuduko, in i Ibikurikira >.
Worked example: Earth around the Sun, μ = 1.327 × 10¹¹ km³/s², a = 149.6 million km. At aphelion r = 152.1 million km:
v = √(1.327 × 10¹¹ × (2/1.521 × 10⁸ − 1/1.496 × 10⁸)) ≈ 29.3 km/s.

- Icyo ari cyo cyose Uburebure, i Umuvuduko A. ni A UMWE Ku Rimwe Akadomo Amahinduka i Ingano: Bya i, na i Ibikurikira > Bigyanye - V.
Kuva: - Na: r = A (1. e):
vp = (1. e) (1. e), v a = (1. e) (1. e)
ni v · v A = μ / a = v, i Umurongo: Umuvuduko ni i * Gitambitse * Bya i Kabiri, OYA i. i Ikibazo.
Gushaka
With the Sun as central body, set a = 1 au and e = 0. Note the speed. Now raise e to 0.6 and compare the fastest and slowest speeds with that number. Is the average of the two equal to the circular speed?

Earth moves about 29.8 km/s around the Sun on average. Roughly how fast at perihelion?
- A 29.3 km/s
- B 30.3 km/s
- C 35 km/s
- D 42 km/s
i
B. 30.3 km/s v_p = √(μ/a · (1+e)/(1−e)) with e = 0.0167 gives about 30.3 km/s.
