Como Explorar o Twilight Types 3D Explorer

Abra o Twilight Types 3D Explorer, mova o mostrador do ângulo de depressão e observe um anel brilhante percorrer as faixas de crepúsculo civil, náutico e astronômico desenhadas em torno do terminador da Terra.

  1. Abra https://freetoolonline.com/space-3d/twilight-types.html e espere a esfera da Terra e as cinco faixas de crepúsculo aparecerem.
  2. Arraste o mostrador do ângulo de depressão de 0 até 18 graus e veja o anel brilhante se mover da calota de luz do dia pelo crepúsculo civil, náutico e astronômico até a noite plena; o painel de informações nomeia a faixa atual.
  3. Arraste o controle de latitude para colocar o marcador verde no ponto de meia-noite local dessa latitude.
  4. Clique em "June solstice (N summer)" para ver quais latitudes têm uma "noite branca" - crepúsculo civil contínuo sem escuridão real.
  5. Clique em "Equinox" ou "December solstice (N winter)" para ver como a depressão à meia-noite da mesma latitude muda com a estação.
  6. Clique em "Reset" para voltar à visualização padrão (mostrador em 6 graus, latitude 64 graus Norte, solstício de junho).
